Currently we always just set the timing to `false` if we aren't
able to analyze a given call expression or new expression. e.g.
```ts
ngOnInit() {
thirdPartyCallSync(() => this.query.doSomething())
}
```
In that case the `thirdPartyCallSync` function comes from the `node_modules`
and is only defined through types while there is no code for the
actual function logic that can be analyzed. This makes it impossible
to tell whether the given call expression actually causes the specified
arrow function to be executed synchronously or not. In order to be able
to make this better, we now peek into the passed arrow function and
check for a synchronous query usage. If so, we set the query timing to
static and mark it as ambiguous. This ensures that the usage strategy is
less "magical" and more correct with third-party code.
Additionally since functions like `setTimeout` are not analyzable but known
to be asynchronous, there is a hard-coded list of known functions which
shouldn't be marked as ambiguous.

Even though we don't run the size-tracking test on CI
right now, we update the golden size map as part of
the size-tracking tool update. The size-map difference
should generally be kept up-to-date to be able to
determine which PRs contribute size to a given file.
PR Close#30257
Based on discussion that happened on the PR that introduced
the size-tracking tool, we want to have another threshold for
the raw byte difference. This allows us to better control for
which changes the size-tracking tool should report a difference.

Currently the static-query migration ignores queries declared on getters
or setters as these are not part of a `PropertyDeclaration`. We need to
handle these queries in order to cover all queries within a given project.
The usage strategy is not able to detect timing for queries on accessors,
so we add a TODO and print a message. The template strategy is able
to detect the proper timing for such queries because it's not dependent
on detecting the usage of the query.

We have an issue where we would like to be able to test perf counter metrics in acceptance tests, but we are unable to do so, because it will break when those same tests are run with ViewEngine. This PR adds a testing utility to `onlyInIvy` that allows for testing of performance counters, and even gives readable errors for what value on `ngDevMode` is incorrect. Has typings for decent autocompletion as well.

This is the final patch to migrate the Angular styling code to have a
smaller instruction set in preparation for the runtime refactor. All
styling-related instructions now work both in template and hostBindings
functions and do not use `element` as a prefix for their names:
BEFORE:
elementStyling()
elementStyleProp()
elementClassProp()
elementStyleMap()
elementClassMap()
elementStylingApply()
AFTER:
styling()
styleProp()
classProp()
styleMap()
classMap()
stylingApply()
PR Close#30318
This patch removes all host-specific styling instructions in favor of
using element-level instructions instead. Because of the previous
patches that made sure `select(n)` worked between styling calls, all
host level instructions are not needed anymore. This patch changes each
of those instruction calls to use any of the `elementStyling*`,
`elementStyle*` and `elementClass*` styling instructions instead.

The static-query template strategy leverages the AOT compiler
in order to determine the query timing. Unfortunately the AOT
compiler has open bugs that can cause unexpected failures which
make the template strategy unusable in rare cases. These rare
exceptions need to be handled gracefully in order to avoid confusion
and to provide a more smooth migration.
Additionally migration strategy setup failures are now reported with
stack traces as the `ng update` command does not print stack traces.
This makes it easier to reproduce and report migration issues.

In an Angular CLI project scenario where projects only reference
top-level source-files through the `tsconfig` `files` option, we currently
do not migrate referenced source-files. This can be fixed checking all
referenced source-files which aren't coming from an external library.
This is similar to how `tslint` determines project source-files.

Currently when someone has a call expression within the `ngOnInit` call
and we try to peek into that function with respect to the current function
context, the schematic errors because a call expression argument is
undefined. This is valid because the target function declaration defines
that parameter with a default value. In order to fix this, we need to
respect parameter default values.

Fixes not being able to bind a `SafeStyle` as a camel cased style property (e.g. `[style.backgroundImage]="someSafeStyle"`). The issue was due to the fact that we only check the dash case property names to determine whether to sanitize a value.

572b54967c changed how the schematic
tests are executed. Tests no longer use the schematic collection
that is also used by the CLI `ng update` command and therefore
the migration collection could technically be invalid.
In order to ensure that the public migration collection is guaranteed
to work and to avoid duplication within two schematic collections, the
changes are partially reverted and only the disabled `injectable-pipe`
schematic has its own collection.

Currently we always prompt when the static-query migration runs. This is not
always needed because some applications do not even use `ViewChild` or
`ContentChild` queries and it just causes confusion if developers need to
decide on a migration strategy while there is nothing to migrate.
In order to avoid this confusion, we no longer prompt for a strategy
if there are no queries declared within the project.

This patch is one commit of many patches that will unify all styling instructions
across both template-level bindings and host-level bindings. This patch in particular
removes the `elementIndex` param because it is already set prior to each styling
instruction via the `select(n)` instruction.

Instead of launching a Node.js process that in turn spawns Bazel binary,
the Builder could now directly spawn the native binary. This makes the
bootup process slightly more efficient, and allows the Builder to
control spawn options. This works with both Bazel and iBazel.

Currently, in jit mode, `ngInjectableDef`, `ngDirectiveDef`, `ngPipeDef` and `ngModuleDef` use `ng://`,
which display them in the top domain in Chrome Dev Tools, whereas `ngComponentDef` uses `ng:///` which display components in a separate domain.
You can currently see:
```
AppModule
UserService
ng://

This commits replaces all `ng://` with `ng:///` to display every Angular entity in the `ng://` domain.

Prior to this patch, the `select(n)` instruction would only be generated
when property bindings are encountered which meant that styling-related
bindings were skipped. This patch ensures that all styling-related bindings
(i.e. class and style bindings) are always prepended with a `select()`
instruction prior to being generated in AOT.

This patch breaks up the existing `elementStylingMap` into
`elementClassMap` and `elementStyleMap` instructions. It also breaks
apart `hostStlyingMap` into `hostClassMap` and `hostStyleMap`
instructions. This change allows for better tree-shaking and reduces
the complexity of the styling algorithm code for `[style]` and `[class]`
bindings.

If an entry-point has a missing dependency then all the entry-points
that would have pointed to that dependency are also removed from
the dependency graph.
Previously we were still processing the dependencies of an entry-point
even if it had already been removed from the graph because it depended
upon a missing dependency that had previously been removed due to another
entry-point depending upon it.
This caused the dependency processing to crash rather than gracefully
logging and handling the missing invalid entry-point.

There was a problem with a combination of the `eager` URL update, browser `back` button, and hybrid applications. Details provided in internal ticket http://b/123667227.
This fix handles the problem by setting `router.browserUrlTree` when all conditions have failed, meaning the browser doesn't do anything with the navigation other than update internal data structures. Without this change, the problem was an old value was stored in `router.broserUrlTree` causing some new navigations to be compared to an old value and breaking future navigations.

In the existing implementation the `elementPropertyInternal` function (meant to
set element properties) was executed even if a bound value didn't change. The
`elementPropertyInternal` was inspecting the incoming value and after comparing it
to `NO_CHANGE` - exiting early. All in all it meant that we were unnecessarily
invoking the `elementPropertyInternal` function for cases where bound value didn't
change.
Based on my bencharks (running change detection without any model update in a tight
loop) this unnecessary function call was causing ~5% slowdown in the change detection
process.
