This commit adds a new `AttributeMarker` type that will be used, in a
future commit, to mark attributes as coming from an inline-template
expansion, rather than the element that is being contained in the template.

This PR also changes the name of `EmptyOutletComponent` to `ɵEmptyOutletComponent`. This is because `ngcc` requires the node to retain the original name while dts bundler will rename the node is it's only exported using the aliases.
Example typings files:
```ts
declare class EmptyOutletComponent {
}
export {EmptyOutletComponent as ɵEmptyOutletComponent}
```
will be emitted as

`ng build` should produce a bundle that could be readily deployed to
a web server, similar to the behavior of current `ng build` with
webpack.
Note that in Bazel, there is no `ng build` for dev bundles. Instead,
users are expected to run `ts_devserver`.

Prior to this change, the RegExp that was used to check for dashes in field names used "g" (global) flag that retains lastIndex, which might result in skipping some fields that should be wrapped in quotes (since lastIndex advanced beyond the next "-" location). This commit removes this flag and updates the test to make sure there are no regressions.

This update gives external tooling the ability for async providers to
finish resolving before the document is serialized. This is not a
breaking change since render already returns a promise. All returned
promises from `BEFORE_APP_SERIALIZED` providers will wait to be
resolved or rejected. Any rejected promises will only console.warn().

Some tests in exports spec rely on the exact output of innerHTML. In IE11 the order of attributes might change, thus causing tests to fail (in case an element contains more than one attribute). This commit avoids innerHTML usage and performs the necessary checks via element properties.

Some of the export tests had assertions that relied on capitalization
of attributes in the DOM. IE treats capitalization somewhat differently,
so our SauceLabs tests were failing.
This commit tweaks the tests so that the assertions do not rely on
attributes to be capitalized or not.

ngtsc occasionally converts a type reference (such as the type of a
parameter in a constructor) to a value reference (argument to a
directiveInject call). TypeScript has a bad habit of sometimes removing
the import statement associated with this type reference, because it's a
type only import when it initially looks at the file.
A solution to this is to always add an import to refer to a type position
value that's imported, and not rely on the existing import.

With 6215799055 we introduced schematics
for `core`, but due to the fact the Saucelabs legacy job does not run
for PRs, we didn't realize that the legacy Saucelabs job ends up
running the schematic specs.
We don't want to run these schematic tests in the legacy-saucelabs job,
as these are node-only specs and the non-Bazel Karma setup is not set
up to provide the devkit schematic node modules.
We exclude the schematics folder in the `core` package in the
legacy-build tsconfig file (similar to how it is done for elements)

Introduces an update schematic for the "@angular/core" package
that automatically migrates pre-V8 "ViewChild" and "ContentChild"
queries to the new explicit timing syntax. This is not required
yet, but with Ivy, queries will be "dynamic" by default. Therefore
specifying an explicit query timing ensures that developers can
smoothly migrate to Ivy (once it's the default).

Previously, if an app version contained the same files as an older
version (e.g. making a change, then rolling it back), the SW would not
detect it as the latest version (and update clients).
This commit fixes it by adding a `timestamp` field in `ngsw.json`, which
makes each build unique (with sufficiently high probability).

When ngtsc generates a .ngfactory shim, it does so based on the contents of
an original file in the program. Occasionally these original files have
comments at the top which are load-bearing (e.g. they contain jsdoc
annotations which are significant to downstream bundling tools). The
generated factory shims should preserve this comment.
This commit adds a step to the ngfactory generator to preserve the top-level
comment from the original source file.

Prior to this change, keys in "inputs" and "outputs" objects generated by compiler were not checked against unsafe characters. As a result, in some cases the generated code was throwing JS error. Now we check whether a given key contains any unsafe chars and wrap it in quotes if needed.

Angular supports having a component extend off of a parent component.
When this happens, all annotation-level data is inherited including styles
and classes. Up until now, Ivy only paid attention to static styling
values on the parent component and not the child component. This patch
ensures that both the parent's component and child component's styling
data is merged and rendered accordingly.

The ngtsc partial evaluator previously would not handle an enum reference
inside a template string expression correctly. Enums are resolved to an
`EnumValue` type, which has a `resolved` property with the actual value.
When effectively toString-ing a `ResolvedValue` as part of visiting a
template expression, the partial evaluator needs to translate `EnumValue`s
to their fully resolved value, which this commit does.

Currently, ngtsc has a bug where if you alias the name of a decorator when
importing it, it won't be detected properly. This is because the compiler
uses the aliased name and not the original, declared name of the decorator
for detection.
This commit fixes the compiler to compare against the declared name of
decorators when available, and adds a test to prevent regression.
PR Close#29061
ngtsc has cyclic import detection, to determine when adding an import to a
directive or pipe would create a cycle. However, this detection must also
account for already inserted imports, as it's possible for both directions
of a circular import to be inserted by Ivy (as opposed to at least one of
those edges existing in the user's program).
This commit fixes the circular import detection for components to take into
consideration already added edges. This is difficult for one critical
reason: only edges to files which will *actually* be imported should be
considered. However, that depends on which directives & pipes are used in
a given template, which is currently only known by running the
TemplateDefinitionBuilder during the 'compile' phase. This is too late; the
decision whether to use remote scoping (which consults the import graph) is
made during the 'resolve' phase, before any compilation has taken place.
Thus, the only way to correctly consider synthetic edges is for the compiler
to know exactly which directives & pipes are used in a template during
'resolve'. There are two ways to achieve this:
1) refactor `TemplateDefinitionBuilder` to do its work in two phases, with
directive matching occurring as a separate step which can be performed
earlier.
2) use the `R3TargetBinder` in the 'resolve' phase to independently bind the
template and get information about used directives.
Option 1 is ideal, but option 2 is currently used for practical reasons. The
cost of binding the template can be shared with template-typechecking.
PR Close#29040
In the @Component decorator, the 'host' field is an object which represents
host bindings. The type of this field is complex, but is generally of the
form {[key: string]: string}. Several different kinds of bindings can be
specified, depending on the structure of the key.
For example:
```
@Component({
host: {'[prop]': 'someExpr'}
})
```
will bind an expression 'someExpr' to the property 'prop'. This is known to
be a property binding because of the square brackets in the binding key.
If the binding key is a plain string (no brackets or parentheses), then it
is known as an attribute binding. In this case, the right-hand side is not
interpreted as an expression, but is instead a constant string.
There is no actual requirement that at build time, these constant strings
are known to the compiler, but this was previously enforced as a side effect
of requiring the binding expressions for property and event bindings to be
statically known (as they need to be parsed). This commit breaks that
relationship and allows the attribute bindings to be dynamic. In the case
that they are dynamic, the references to the dynamic values are reflected
into the Ivy instructions for attribute bindings.
PR Close#29033
DynamicValues are generated whenever a partially evaluated expression is
unable to be resolved statically. They contain a reference to the ts.Node
which wasn't resolvable.
They can also be nested. For example, the expression 'a + b' is resolvable
only if 'a' and 'b' are themselves resolvable. If either 'a' or 'b' resolve
to a DynamicValue, the whole expression must also resolve to a DynamicValue.
Previously, if 'a' resolved to a DynamicValue, the entire expression might
have been resolved to the same DynamicValue. This correctly indicated that
the expression wasn't resolvable, but didn't return a reference to the
shallow node that couldn't be resolved (the expression 'a + b'), only a
reference to the deep node that couldn't be resolved ('a').
In certain situations, it's very useful to know the shallow unresolvable
node (for example, to use it verbatim in the output). To support this,
the partial evaluator is updated to always wrap DynamicValue to point to
each unresolvable expression as it's processed, ensuring the receiver can
determine exactly which expression node failed to resolve.

Currently if a user accidentally calls ViewContainerRef.insert() with
a view that has already been attached, we do not clean up the references
properly, so we create a view tree with a cycle. This causes an infinite
loop when the view is destroyed.
This PR ensures that we fall back to ViewContainerRef.move() behavior
if we try to insert a view that is already attached. This fixes the
cycle and honors the user intention.
