When using `platformBrowserDynamic().bootstrapModule()`, it is possible
to set `defaultEncapsulation` and `preserveWhitespaces` as default
configuration to influence how components are compiled. When compiling
components in JIT with Ivy, these options were not taken into account.
This commit publishes the options to be globally available, so that the
lazy compilation of JIT components has access to the configured
bootstrap options. Note that this approach does not allow changing the
options once they have been set, as Ivy's compilation model does not
allow for multiple compilations to exist at the same time.
For applications that bootstrap multiple modules, it is now required
to provide the exact same bootstrap options. An error is logged if
incompatible bootstrap options are provided, in which case the updated
options will be ignored.

When two entry-points overlap, ngcc may attempt to process some
files twice. Previously, when this occured ngcc would just exit with an
error preventing any other entry-points from being processed.
This commit changes ngcc so that if `errorOnFailedEntryPoint` is false, it will
simply log an error and continue to process entry-points. This is useful when
ngcc is processing the entire node_modules folder and there are some invalid
entry-points that the project doesn't actually use.
PR Close#36083
Previously, when an entry-point contained code that caused its compilation
to fail, ngcc would exit in the middle of processing, possibly leaving other
entry-points in a corrupt state.
This change adds a new `errorOnFailedEntryPoint` option to `mainNgcc` that
specifies whether ngcc should exit immediately or log an error and continue
processing other entry-points.
The default is `false` so that ngcc will not error but continue processing
as much as possible. This is useful in post-install hooks, and async CLI
integration, where we do not have as much control over which entry-points
should be processed.
The option is forced to true if the `targetEntryPointPath` is provided,
such as the sync integration with the CLI, since in that case it is targeting
an entry-point that will actually be used in the current project so we do want
ngcc to exit with an error at that point.

Later when we implement the ability to continue processing when tasks have
failed to compile, we will also need to avoid processing tasks that depend
upon the failed task.
This refactoring exposes this list of dependent tasks in a way that can be
used to skip processing of tasks that depend upon a failed task.
It also changes the blocking model of the parallel mode of operation so
that non-typings tasks are now blocked on their corresponding typings task.
Previously the non-typings tasks could be triggered to run in parallel to
the typings task, since they do not have a hard dependency on each other,
but this made it difficult to skip task correctly if the typings task failed,
since it was possible that a non-typings task was already in flight when
the typings task failed. The result of this is a small potential degradation
of performance in async parallel processing mode, in the rare cases that
there were not enough unblocked tasks to make use of all the available
workers.

When ngcc is compiling an entry-point, it uses a `ReflectionHost` that
is specific to its format, e.g. ES2015, ES5, UMD or CommonJS. During the
compilation of that entry-point however, the reflector may be used to
reflect into external libraries using their declaration files.
Up until now this was achieved by letting all `ReflectionHost` classes
consider their parent class for reflector queries, thereby ending up in
the `TypeScriptReflectionHost` that is a common base class for all
reflector hosts. This approach has proven to be prone to bugs, as
failing to call into the base class would cause incompatibilities with
reading from declaration files.
The observation can be made that there's only two distinct kinds of
reflection host queries:
1. the reflector query is about code that is part of the entry-point
that is being compiled, or
2. the reflector query is for an external library that the entry-point
depends on, in which case the information is reflected
from the declaration files.
The `ReflectionHost` that was chosen for the entry-point should serve
only reflector queries for the first case, whereas a regular
`TypeScriptReflectionHost` should be used for the second case. This
avoids the problem where a format-specific `ReflectionHost` fails to
handle the second case correctly, as it isn't even considered for such
reflector queries.
This commit introduces a `ReflectionHost` that delegates to the
`TypeScriptReflectionHost` for AST nodes within declaration files,
otherwise delegating to the format-specific `ReflectionHost`.

Currently, when Angular code is built with Bazel and with Ivy, generated
factory shims (.ngfactory files) are not processed via the majority of
tsickle's transforms. This is a subtle effect of the build infrastructure,
but it boils down to a TsickleHost method `shouldSkipTsickleProcessing`.
For ngc_wrapped builds (Bazel + Angular), this method is defined in the
`@bazel/typescript` (aka bazel rules_typescript) implementation of
`CompilerHost`. The default behavior is to skip tsickle processing for files
which are not present in the original `srcs[]` of the build rule. In
Angular's case, this includes all generated shim files.
For View Engine factories this is probably desirable as they're quite
complex and they've never been tested with tsickle. Ivy factories however
are smaller and very straightforward, and it makes sense to treat them like
any other output.
This commit adjusts two independent implementations of
`shouldSkipTsickleProcessing` to enable transformation of Ivy shims:
* in `@angular/bazel` aka ngc_wrapped, the upstream `@bazel/typescript`
`CompilerHost` is patched to treat .ngfactory files the same as their
original source file, with respect to tsickle processing.
It is currently not possible to test this change as we don't have any test
that inspects tsickle output with bazel. It will be extensively tested in
g3.
* in `ngc`, Angular's own implementation is adjusted to allow for the
processing of shims when compiling with Ivy. This enables a unit test to
be written to validate the correct behavior of tsickle when given a host
that's appropriately configured to process factory shims.
For ngtsc-as-a-plugin, a similar fix will need to be submitted upstream in
tsc_wrapped.

This commit performs a few updates to internal functions that would be required in upcoming changes to support synthetic host bindings in Directives.
* the `elementPropertyInternal` function was refactored to accept renderer as an argument (prior to that, there was a function that loads the renderer in some specific way for animation bindings)
* `elementPropertyInternal`, `elementAttributeInternal` and `listenerInternal` functions were updated to have a fixed set of arguments (for better performance)
* `elementPropertyInternal` and `elementAttributeInternal` functions were updated to take `tNode` as an argument instead of passing node index (that was used to retrieve `tNode` internally), in some cases we already have `tNode` available or we can retrieve it from the state
The refactoring was triggered by the need to pass different renderers to the `elementPropertyInternal` to support synthetic host bindings in Directives (see this comment for additional context: https://github.com/angular/angular/pull/35568/files#r388034584).

This has a couple benefits:
- we now use a .bazelversion file rather than package.json to pin the version of bazel we want. This means even if you install bazel on your computer rather than via yarn, you'll still get a warning if your bazel version is wrong.
- you no longer end up downloading three copies of bazel due to bugs in both npm and yarn where they download all tarballs before checking the metadata to see which are usable on the local platform.
- bazelisk correctly handles the tools/bazel trick for wrapping functionality, which we want to use to instrument developer build latencies

To create the symbols of a module, the static symbol resolver first gets
all the symbols loaded in the module by an export statement. For `export
* from './module'`-like statements, all symbols from `./module` must be
loaded. In cases where the exporting module is actually the same module
that the export statement is in, this causes an unbounded recursive
resolution of the same module.
Exports of the same module are not needed, as their symbols will be
resolved when the symbols in the module metadata's `metadata` key is
explored.
This commit resolves the unbounded recursion by loading exporting
modules only if they differ from the module currently being resolved.

By default, `zone.js` wrap uncaught promise error and wrap it to a new Error object with some
additional information includes the value of the error and the stack trace.
Consider the following example:
```
Zone.current
.fork({
name: 'promise-error',
onHandleError: (delegate: ZoneDelegate, current: Zone, target: Zone, error: any): boolean => {
console.log('caught an error', error);
delegate.handleError(target, error);
return false;
}
}).run(() => {
const originalError = new Error('testError');
Promise.reject(originalError);
});
```
The `promise-error` zone catches a wrapped `Error` object whose `rejection` property equals
to the original error, and the message will be `Uncaught (in promise): testError....`,
You can disable this wrapping behavior by defining a global configuraiton
`__zone_symbol__DISABLE_WRAPPING_UNCAUGHT_PROMISE_REJECTION = true;` before importing `zone.js`.

Prior to this commit, i18n runtime logic relied on the assumption that provided translation is syntactically correct, specifically around ICU syntax. However provided translations might contain some errors that lead to parsing failure. Specifically when translation contains curly braces, runtime i18n logic tries to parse them as an ICU expression and fails. This commit validates ICU parsing result (making sure it was parsed correctly) and throws an error if parsing error happens. The error that is thrown also contains translated message text for easier debugging.
Note: the check and the error message introduced in this PR is a safeguard against the problem that led to unhandled i18n runtime logic crash. So the framework behavior remains the same, we just improve the error message and it should be safe to merge to the patch branch.
