This commit fixes a bug where we assumed all dynamically created
components would have tag-name selectors, so we passed through the
"tag name" to the renderer as the first index of the selector. For
components with attribute selectors, the tag name would be "", so
the renderer would try to create an element with tag name "" and
throw. Now we default to a "div" element the same way that View
Engine did.

Moves all google3 migration tslint rules into a single directory.
This makes it easier to wire up multiple migration rules in
google3 without having to update the rule directories each time
a new migration is available.
PR Close#30956
Introduces a new migration schematic for adding the "@Injectable()"
decorator to provider classes which are currently not migrated. Previously
in ViewEngine, classes which are declared as providers sometimes don't
require the "@Injectable()" decorator
(e.g. https://stackblitz.com/edit/angular-hpo7gw)
With Ivy, provider classes need to be explicitly decorated with
the "@Injectable()" decorator if they are declared as providers
of a given module. This commit introduces a migration schematic
which automatically adds the explicit decorator to places where
the decorator is currently missing.
The migration logic is designed in a CLI devkit and TSlint agnostic
way so that we can also have this migration run as part of a public
CLI migration w/ `ng update`. This will be handled as part of a follow-up to reiterate on console output etc.

The way the `ComponentFactory.create` is set up at the moment is that if a `rootSelectorOrNode` is passed in, the root context will be injected instead of creating dedicated one for the component. As far as I can tell, there doesn't seem to be a reason to do this and nothing seems to break because of it. These changes switch to always create the root context.

In ViewEngine nodes that were inserted through `Renderer2` would also be picked up by `DebugNode.query` and `DebugNode.queryAll`. This worked because everything in ViewEngine went through `Renderer2` and `DebugRenderer2` in dev mode which was able to keep track of the child nodes as they're being inserted. This no longer works in Ivy, because we don't use `DebugRenderer2` and debug nodes work a little differently. These changes work around the issue by walking the DOM as the logical tree is being walked and looking for matches. Note that this is __not__ optimal, because we're walking similar trees multiple times. ViewEngine could do it more efficiently, because all the insertions go through Renderer2, however that's not the case in Ivy. This approach is being used because:
1. Matching the ViewEngine behavior would mean potentially introducing a depedency from `Renderer2` to Ivy which could bring Ivy code into ViewEngine.
2. We would have to make `Renderer3` "know" about debug nodes.
3. It allows us to capture nodes that were inserted directly via the DOM.

When injecting a `ChangeDetectorRef` into a pipe, the expected result is that the ref will be tied to the component in which the pipe is being used. This works for most cases, however when a pipe is used inside a property binding of a component (see test case as an example), the current `TNode` is pointing to component's host so we end up injecting the inner component's view. These changes fix the issue by only looking up the component view of the `TNode` if the `TNode` is a parent.

patch is a follow up patch to that and removes all old, unused

This commit fixes a bug where ICU expressions inserted into ngTemplateOutlets
that are inside ngFor blocks would throw an error. We were assuming in view
insertion code that text nodes would always exist by the time a view\`s
creation block had executed. This is not true for text nodes created dynamically
by ICUs because this happens in the update block (in `i18nApply`).
This change ensures such dynamically created nodes are skipped when encountered
too early (as they will be attached later by i18n code anyway).

We currently have a handwritten version of the Ivy directive def for NgClass so
we can switch between Ivy and View Engine behavior. This generated code needs to
be kept up-to-date with what the Ivy compiler generates.
PR 30742 recently changed `classMap` such that it now requires allocation of
host binding slots. This means that the `allocHostVars()` function must be
called in the NgClass directive def to match compiler output, but the
handwritten directive def was not updated. This caused a bug where NgClass
was inappropriately overwriting data for other directives because space was
not allocated for its values.

This commit is the final patch of the ivy styling algorithm refactor.
This patch swaps functionality from the old styling mechanism to the

Fixes all TypeScript failures caused by enabling the `--strict`
flag for test source files. We also want to enable the strict
options for tests as the strictness enforcement improves the
overall codehealth, unveiled common issues and additionally it
allows us to enable `strict` in the `tsconfig.json` that is picked
up by IDE's.

In View Engine, developers can pass bootstrap and entry components
as nested arrays. e.g.
```ts
export const MyOtherEntryComponents = [A, B, C]
@NgModule({
entryComponents: [MyComp, MyOtherEntryComponents]
})
```
Currently using nested arrays for these properties causes
unexpected errors to be reported in Ivy since the semantic
NgModule checks aren't properly recursing into the nested
entry/bootstrap components. This issue has been unveiled by
enabling the strict function parameter checks.

Currently the `ɵɵdefineComponent` method has incorrect type
definitions the `directives` and `pipes` metadata property.
The incorrect types allow developers to pass in already instantiated
`DirectiveDef` or `ComponentDef` objects. This can cause unexpected
failures because the definition internally only expects `Type` objects
and now incorrectly tries to read the `ngDirectiveDef` or `ngComponentDef`
of existing definitions.
This issue has been unveiled by enabling the strict function parameter
types flag, where the directive definitions are determined from each array
element in the `directives` or `pipes` property (which can throw).

Fixes Ivy matching directives against attribute bindings (e.g. `[attr.some-directive]="foo"`). Works by excluding attribute bindings from the attributes array during compilation. This has the added benefit of generating less code.
**Note:** My initial approach to implementing this was to have a different marker for attribute bindings so that they can be ignored when matching directives, however as I was implementing it I realized that the attributes in that array were only used for directive matching (as far as I could tell). I decided to drop the attribute bindings completely, because it results in less generated code.

PR Close#31519
Currently we reuse the same instruction both for regular property bindings and property bindings on the `host`. The only difference between the two is that when it's on the host we shouldn't support inputs. We have an optional parameter called `nativeOnly` which is used to differentiate the two, however since `nativeOnly` is preceeded by another optional parameter (`sanitizer`), we have to generate two extra parameters for each host property bindings every time (e.g. `property('someProp', 'someValue', null, true)`).
These changes add a new instruction called `hostProperty` which avoids the need for the two parameters by removing `nativeOnly` which is always set and it allows us to omit `sanitizer` when it isn't being used.
These changes also remove the `nativeOnly` parameter from the `updateSyntheticHostBinding` instruction, because it's only generated for host elements which means that we can assume that its value will always be `true`.

Prior to this fix, the logic to set the right placeholder format for ICUs was a bit incorrect: if there was a nested ICU in one of the root ICU cases, that led to a problem where placeholders in subsequent branches used the wrong ({$placeholder}) format instead of {PLACEHOLDER} one. This commit updates the logic to make sure we properly transform all placeholders even if nested ICUs are present.

Since `goog.getMsg` does not process ICUs (post-processing is required via goog.i18n.MessageFormat, https://google.github.io/closure-library/api/goog.i18n.MessageFormat.html) and placeholder format used for ICUs and regular messages inside `goog.getMsg` are different, the current implementation (that assumed the same placeholder format) needs to be updated. This commit updates placeholder format used inside ICUs from `{$placeholder}` to `{PLACEHOLDER}` to better align with Closure. ICU placeholders (that were left as is prior to this commit) are now replaced with actual values in post-processing step (inside `i18nPostprocess`).

Adds a schematic and tslint rule that automatically migrate the consumer from `Renderer` to `Renderer2`. Supports:
* Renaming imports.
* Renaming property and method argument types.
* Casting to `Renderer`.
* Mapping all of the methods from the `Renderer` to `Renderer2`.
Note that some of the `Renderer` methods don't map cleanly between renderers. In these cases the migration adds a helper function at the bottom of the file which ensures that we generate valid code with the same return value as before. E.g. here's what the migration for `createText` looks like.
Before:
```
class SomeComponent {
createAndAddText() {
const node = this._renderer.createText(this._element.nativeElement, 'hello');
node.textContent += ' world';
}
}
```
After:
```
class SomeComponent {
createAndAddText() {
const node = __rendererCreateTextHelper(this._renderer, this._element.nativeElement, 'hello');
node.textContent += ' world';
}
}
function __rendererCreateTextHelper(renderer: any, parent: any, value: any) {
const node = renderer.createText(value);
if (parent) {
renderer.appendChild(parent, node);
}
return node;
}

Adds the new `classMapInterpolate1` through `classMapInterpolate8` instructions which handle interpolations inside the `class` attribute and moves the interpolation logic internally. This allows us to remove the `interpolationX` instructions in a follow-up PR.
These changes also add an error if an interpolation is encountered inside a `style` tag (e.g. `style="width: {{value}}"`). Up until now this would actually generate valid instructions, because `styleMap` goes through the same code path as `classMap` which does support interpolation. At runtime, however, `styleMap` would set invalid styles that look like `<div style="0:w;1:i;2:d;3:t;4:h;5::;7:1;">`. In `ViewEngine` interpolations inside `style` weren't supported either, however there we'd output invalid styles like `<div style="unsafe">`, even if the content was trusted.

When a class uses Angular decorators such as `@Input`, `@Output` and
friends without an Angular class decorator, they are compiled into a
static `ngBaseDef` field on the class, with the TypeScript declaration
of the class being altered to declare the `ngBaseDef` field to be of type
`ɵɵBaseDef`. This type however requires a generic type parameter that
corresponds with the type of the class, however the compiler did not
provide this type parameter. As a result, compiling a program where such
invalid `ngBaseDef` declarations are present will result in compilation
errors.
This commit fixes the problem by providing the generic type parameter.
