Miško Hevery ab931cf872 fix(ivy): host-styling throws assert exception inside *ngFor (#35133)
Inside `*ngFor` the second run of the styling instructions can get into situation where it tries to read a value from a binding which has not yet executed. As a result the read is `NO_CHANGE` value and subsequent property read cause an exception as it is of wrong type.

Misko Hevery 01308e4c7c refactor(ivy): Remove `TNode.directives` in favor of `TData` (#35050)
`TNode.directives` was introduced in https://github.com/angular/angular/pull/34938. Turns out that it is unnecessary because the information is already present it `TData` when combining with `TNode.directiveStart` and `TNode.directiveEnd`

Mainly this is true (conceptually):
```
expect(tNode.directives).toEqual(
    tData.slice(
        tNode.directivesStart,
        tNode.directivesEnd - tNode.DirectivesStart -1
    )
);
```

The refactoring removes `TNode.directives` and adds `TNode.directiveStyling` as we still need to keep location in the directive in `TNode`

Misko Hevery ee8b8f52aa feat(ivy): Change static priority resolution to be same level as directive it belongs to (#34938)
This change changes the priority order of static styling.

Current priority:
```
(least priority)
- Static
  - Component
  - Directives
  - Template
- Dynamic Binding
  - Component
    - Map/Interpolation
    - Property
  - Directives
    - Map/Interpolation
    - Property
  - Template
    - Map/Interpolation
    - Property
(highest priority)
```

The issue with the above priority is this use case:

```
<div style="color: red;" directive-which-sets-color-blue>
```
In the above case the directive will win and the resulting color will be `blue`. However a small change of adding interpolation to the example like so. (Style interpolation is coming in https://github.com/angular/angular/pull/34202)
```
<div style="color: red; width: {{exp}}px" directive-which-sets-color-blue>
```
Changes the priority from static binding to interpolated binding which means now the resulting color is `red`. It is very surprising that adding an unrelated interpolation and style can change the `color` which was not changed. To fix that we need to make sure that the static values are associated with priority of the source (directive or template) where they were declared. The new resulting priority is:

```
(least priority)
- Component
  - Static
  - Map/Interpolation
  - Property
- Directives
  - Static
  - Map/Interpolation
  - Property
- Template
  - Static
  - Map/Interpolation
  - Property
(highest priority)
```

George Kalpakas 669df70da5 fix(ivy): ensure `DebugNode`/`DebugElement` are tree-shakeable in Ivy (#35003)
There are different `DebugNode`/`DebugElement` implementations (and
associated helper functions) for ViewEngine and Ivy. Additionally, these
classes/functions, which are defined inside the `core` package, are
imported by the `platform-browser` package.

Previously, this code was not tree-shaken as expected in Ivy. #30130
partially addressed the issue, but only for the case where `core` and
`platform-browser` end up in the same closure after webpack's scope
hoisting. In cases where this is not the case, our webpack/terser based
tooling is not capable of tree-shaking it.

This commit fixes the problem, by ensuring that the code retained in Ivy
mode (due to the cross-package import) does not unnecessarily reference
`DebugNode`/`DebugElement`, allowing the code to be tree-shaken away.
This results in a 7.6KB reduction in the size of the main angular.io
bundle.

Miško Hevery 9bd9590767 refactor(ivy): change styling to use programmatic API on updates (#34804)
Previously we would write to class/style as strings `element.className` and `element.style.cssText`. Turns out that approach is good for initial render but not good for updates. Updates using this approach are problematic because we have to check to see if there was an out of bound write to style and than perform reconciliation. This also requires the browser to bring up CSS parser which is expensive.

Another problem with old approach is that we had to queue the DOM writes and flush them twice. Once on element advance instruction and once in `hostBindings`. The double flushing is expensive but it also means that a directive can observe that styles are not yet written (they are written after directive executes.)

The new approach uses `element.classList.add/remove` and `element.style.setProperty/removeProperty` API for updates only (it continues to use `element.className` and `element.style.cssText` for initial render as it is cheaper.) The other change is that the styling changes are applied immediately (no queueing). This means that it is the instruction which computes priority. In some circumstances it may result in intermediate writes which are than overwritten with new value. (This should be rare)

Overall this change deletes most of the previous code and replaces it with new simplified implement. The simplification results in code savings.

Miško Hevery 5aabe93abe refactor(ivy): Switch styling to new reconcile algorithm (#34616)
NOTE: This change must be reverted with previous deletes so that it code remains in build-able state.

This change deletes old styling code and replaces it with a simplified styling algorithm.

The mental model for the new algorithm is:
- Create a linked list of styling bindings in the order of priority. All styling bindings ere executed in compiled order and than a linked list of bindings is created in priority order.
- Flush the style bindings at the end of `advance()` instruction. This implies that there are two flush events. One at the end of template `advance` instruction in the template. Second one at the end of `hostBindings` `advance` instruction when processing host bindings (if any).
- Each binding instructions effectively updates the string to represent the string at that location. Because most of the bindings are additive, this is a cheap strategy in most cases. In rare cases the strategy requires removing tokens from the styling up to this point. (We expect that to be rare case)S Because, the bindings are presorted in the order of priority, it is safe to resume the processing of the concatenated string from the last change binding.

Miško Hevery 2961bf06c6 refactor(ivy): move `hostVars`/`hostAttrs` from instruction to `DirectiveDef` (#34683)
This change moves information from instructions to declarative position:
- `ɵɵallocHostVars(vars)` => `DirectiveDef.hostVars`
- `ɵɵelementHostAttrs(attrs)` => `DirectiveDef.hostAttrs`

When merging directives it is necessary to know about `hostVars` and `hostAttrs`. Before this change the information was stored in the `hostBindings` function. This was problematic, because in order to get to the information the `hostBindings` would have to be executed. In order for `hostBindings` to be executed the directives would have to be instantiated. This means that the directive instantiation would happen before we had knowledge about the `hostAttrs` and as a result the directive could observe in the constructor that not all of the `hostAttrs` have been applied. This further complicates the runtime as we have to apply `hostAttrs` in parts over many invocations.

`ɵɵallocHostVars` was unnecessarily complicated because it would have to update the `LView` (and Blueprint) while existing directives are already executing. By moving it out of `hostBindings` function we can access it statically and we can create correct `LView` (and Blueprint) in a single pass.

This change only changes how the instructions are generated, but does not change the runtime much. (We cheat by emulating the old behavior by calling `ɵɵallocHostVars` and `ɵɵelementHostAttrs`) Subsequent change will refactor the runtime to take advantage of the static information.

Misko Hevery 76698d38f7 refactor(ivy): Add style reconciliation algorithm (#34004)
This change introduces class/style reconciliation algorithm for DOM elements.
NOTE: The code is not yet hooked up, it will be used by future style algorithm.

Background:
Styling algorithm currently has [two paths](https://hackmd.io/@5zDGNGArSxiHhgvxRGrg-g/rycZk3N5S)
when computing how the style should be rendered.
1. A direct path which concatenates styling and uses `elemnent.className`/`element.style.cssText` and
2. A merge path which uses internal data structures and uses `element.classList.add/remove`/`element.style[property]`.

The situation is confusing and hard to follow/maintain. So a future PR will remove the merge-path and do everything with
direct-path. This however breaks when some other code adds class or style to the element without Angular's knowledge.
If this happens instead of switching from direct-path to merge-path algorithm, this change provides a different mental model
whereby we always do `direct-path` but the code which writes to the DOM detects the situation and reconciles the out of bound write.

The reconciliation process is as follows:
1. Detect that no one has modified `className`/`cssText` and if so just write directly (fast path).
2. If out of bounds write did occur, switch from writing using `className`/`cssText` to `element.classList.add/remove`/`element.style[property]`.
   This does require that the write function computes the difference between the previous Angular expected state and current Angular state.
   (This requires a parser. The advantage of having a parser is that we can support `style="width: {{exp}}px" kind of bindings.`)
   Compute the diff and apply it in non destructive way using `element.classList.add/remove`/`element.style[property]`

Properties of approach:
- If no out of bounds style modification:
  - Very fast code path: Just concatenate string in right order and write them to DOM.
  - Class list order is preserved
- If out of bounds style modification detected:
  - Penalty for parsing
  - Switch to non destructive modification: `element.classList.add/remove`/`element.style[property]`
  - Switch to alphabetical way of setting classes.

Pete Bacon Darwin e0ad9ecda0 fix(ivy): ensure that `LOCALE_ID` is set after app initializers (#34830)
Before ivy it was possible to configure a mutable service value
in an application initializer (by providing an `APP_INITIALIZER`)
that could be read in the provider of `LOCALE_ID`. This is a common
scenario if you wanted to load the locale id asynchronously from
an HTTP request for instance.

When using the ivy, the runtime needs to be told what the current
locale is, which is done by calling the `setLocaleId()` function with
the value injected by the `LOCALE_ID` token. Previously this was
being done before the application initializers were run, which meant
that the `LOCALE_ID` provider was being executed before the
app initializers had a chance to get a new value for it.

Now this initalization of the locale for the ivy runtime is done after the
application initializers have been run.
