This fix corrects a bug where we were passing a binding _value_
in place of an expected binding index. This reulted in the binding
value being compared to an array length and buggy type coercion.
Fixing this bug speeds up test scenario by ~10-15%.

Previously, several `ngtsc` and `ngcc` APIs dealing with class
declaration nodes used inconsistent types. For example, some methods of
the `DecoratorHandler` interface expected a `ts.Declaration` argument,
but actual `DecoratorHandler` implementations specified a stricter
`ts.ClassDeclaration` type.
As a result, the stricter methods would operate under the incorrect
assumption that their arguments were of type `ts.ClassDeclaration`,
while the actual arguments might be of different types (e.g. `ngcc`
would call them with `ts.FunctionDeclaration` or
`ts.VariableDeclaration` arguments, when compiling ES5 code).
Additionally, since we need those class declarations to be referenced in
other parts of the program, `ngtsc`/`ngcc` had to either repeatedly
check for `ts.isIdentifier(node.name)` or assume there was a `name`
identifier and use `node.name!`. While this assumption happens to be
true in the current implementation, working around type-checking is
error-prone (e.g. the assumption might stop being true in the future).
This commit fixes this by introducing a new type to be used for such
class declarations (`ts.Declaration & {name: ts.Identifier}`) and using
it consistently throughput the code.

Previously, it was not possible to have multiple apps (using
`@angular/service-worker`) on different subpaths of the same domain,
because each SW would overwrite the caches of the others (even though
their scope was different).
This commit fixes it by ensuring that the cache names created by the SW
are different for each scope.

The tests will not be run anyway, so the artifacts are never used and
there might be errors if creating the testing artifacts relies on APIs
that are not available in that environment (e.g. `URL`).

Previously, only directives and services with generic type parameters
would emit `any` as generic type when emitting Ivy metadata into .d.ts
files. Pipes can also have generic type parameters but did not emit
`any` for all type parameters, resulting in the omission of those
parameters which causes compilation errors.
This commit adds support for pipes with generic type arguments and emits
`any` as generic type in the Ivy metadata.

This commit adds a `NewEntryPointFileWriter` that will be used in
webpack integration. Instead of overwriting files in-place, this `FileWriter`
will make a copy of the TS program files and write the transformed files
there. It also updates the package.json with new properties that can be
used to access the new entry-point format.

If `targetEntryPointPath` is provided to `mainNgcc` then we will now mark all
the `propertiesToConsider` for that entry-point if we determine that
it does not contain code that was compiled by Angular (for instance it has
no `...metadata.json` file).
The commit also renames `__modified_by_ngcc__` to `__processed_by_ivy_ngcc__`, since
there may be entry-points that are marked despite ngcc not actually compiling anything.

Now we check the build-marker version for all the formats
rather than just the one we are going to compile.
This way we don't get into the situation where one format was
built with one version of ngcc and another format was built with
another version.

Now the public API does not contain internal types, such as `AbsoluteFsPath` and
`EntryPointJsonProperty`. Instead we just accept strings and then guard them in
`mainNgcc` as appropriate.
A new public API function (`hasBeenProcessed`) has been exported to allow programmatic
checking of the build marker when the package.json contents are already known.

Previously we always considered all the properties in the package.json
if no `propertiesToConsidere` were provided.
But this results in computing a new set of properties for each entry-point
plus iterating through many of the package.json properties that are
not related to bundle-format paths.

Sometimes, in ESM5 code, aliases to exported variables are used internally
to refer to the exported value. This prevented some analysis from being
able to match up a reference to an export to the actual export itself.
For example in the following code:
```
var HttpClientXsrfModule = /** @class */ (function () {
function HttpClientXsrfModule() {
}
HttpClientXsrfModule_1 = HttpClientXsrfModule;
HttpClientXsrfModule.withOptions = function (options) {
if (options === void 0) { options = {}; }
return {
ngModule: HttpClientXsrfModule_1,
providers: [],
};
};
var HttpClientXsrfModule_1;
HttpClientXsrfModule = HttpClientXsrfModule_1 = tslib_1.__decorate([
NgModule({
providers: [],
})
], HttpClientXsrfModule);
return HttpClientXsrfModule;
}());
```
We were not able to tell that the `ngModule: HttpClientXsrfModule_1` property
assignment was actually meant to refer to the `function HttpClientXrsfModule()`
declaration. This caused the `ModuleWithProviders` processing to fail.
This commit ensures that we can compile typings files using the ESM5
format, so we can now update the examples boilerplate tool so that it
does not need to compile the ESM2015 format at all.

In ESM5 code, static methods appear as property assignments onto the constructor
function. For example:
```
var MyClass = (function() {
function MyClass () {}
MyClass.staticMethod = function() {};
return MyClass;
})();
```
This commit teaches ngcc how to process these forms when searching
for `ModuleWithProviders` functions that need to be updated in the typings
files.

By default ngcc will compile all the format properties specified. With this
change you can configure ngcc so that it will stop compiling an entry-point
after the first property that matches the `propertiesToConsider`.

By ensuring that EntryPointBundle contains everything that `Transformer.transform()`
needs to do its work, we can simplify its signature.

Now that we are using package.json properties to indicate which
entry-point format to compile, it turns out that we don't really
need to distinguish between flat and non-flat formats, unless we
are compiling `@angular/core`.
PR Close#29092
You can now specify a list of properties in the package.json that
should be considered (in order) to find the path to the format to compile.
The build marker system has been updated to store the markers in
the package.json rather than an additional external file.
Also instead of tracking the underlying bundle format that was compiled,
it now tracks the package.json property.
BREAKING CHANGE:
The `proertiesToConsider` option replaces the previous `formats` option,
which specified the final bundle format, rather than the property in the
package.json.
If you were using this option to compile only specific bundle formats,
you must now modify your usage to pass in the properties in the package.json
that map to the format that you wish to compile.
In the CLI, the `--formats` is no longer available. Instead use the
`--properties` option.

You can now, programmatically, specify an entry-point where
the ngcc compilation will occur.
Only this entry-point and its dependencies will be compiled.

The `mainNgcc()` function has been refactored to make it easier to call
ngcc from JavaScript, rather than via the command line.
For example, the `yargs` argument parsing and the exception
handling/logging have moved to the `main-ngcc.ts`
file so that it is only used for the command line version.

Previously we only compiled the typings files, in ngcc, if there was
an ES2015 formatted bundle avaiable. This turns out to be an artificial
constraint and we can also support typings compilation via ES5 formats
too.
This commit changes the ngcc compiler to attempt typings compilation
via ES5 if necessary. The order of the formats to consider is now:
FESM2015, FESM5, ESM2015, ESM5.
