Binding metadata are only needed:
- for property bindings;
- when TestBed tests are being run.
This commit guards binding metadata storage with the ngDevMode flag
which saves ~6% of a proerty binding processing time in the production
mode (and reduces bundle size).

After a series of recent refactorings `enterView` and `leaveView` became
identical. This PR merges both into one concept of view selectio (similar
to a node selection). This reduces number of concepts and code size.
PR Close#32263
This commit removes all the (duplicated) logic of setting lView[BINDING_INDEX]
from `enterView`. `enterView` is on the critcal path perf-wise so we should
avoid having any logic in there and minimise memory read / write.
This simple refactoring in this PR reduces time spent in noop change detection
by ~12% (from ~800ms down to ~700ms on a local machine where measurements were
taken).

When ngcc is called for a specific entry-point, it has to determine
which dependencies to transitively process. To accomplish this, ngcc
traverses the full import graph of the entry-points it encounters, for
which it uses a dependency host to find all module imports. Since
imports look different in the various bundle formats ngcc supports, a
specific dependency host is used depending on the information provided
in an entry-points `package.json` file. If there's not enough
information in the `package.json` file for ngcc to be able to determine
which dependency host to use, ngcc would fail with an error.
If, however, the entry-point is not compiled by Angular, it is not
necessary to process any of its dependencies. None of them can have
been compiled by Angular so ngcc does not need to know about them.
Therefore, this commit changes the behavior to avoid recursing into
dependencies of entry-points that are not compiled by Angular.
In particular, this fixes an issue for packages that have dependencies
on the `date-fns` package. This package has various secondary
entry-points that have a `package.json` file only containing a `typings`
field, without providing additional fields for ngcc to know which
dependency host to use. By not needing a dependency host at all, the
error is avoided.

This PR makes finding class declarations properties in decorators are
applied to more generic to all properties that may be in a decorator,
and adds helper methods enabling getting the property assignment of a
property value and verifying that a property assignment is actually in a
decorator applied to a class.
This is done so that it will be easier to provide Angular definitions
for decorator properties moving forward. Most immediately, this will
provide decorator class verification for #32238.

The TemplateInfo type is an extension of AstResult, but it is not
necessary at all. Instead, improve the current interface for AstResult
by removing all optional fileds and include the TemplateSource in
AstResult instead.

Prior to this change, the `BINDING_INDEX` of a given lView was reset after processing a template. However change detection can be triggered as a result of View queries processing, thus leading to subsequent `refreshView` call (and executing a template), which in turn operates with the binding index that is not reset after the previous `refreshView` call. This commit updates the logic to reset binding index before we execute a template, so binding index is correct for instructions inside template function.

In ngc is was valid to set the "flatModuleOutFile" option to "null". This is sometimes
necessary if a tsconfig extends from another one but the "fatModuleOutFile" option
needs to be unset (note that "undefined" does not exist as value in JSON)
Now if ngtsc is used to compile the project, ngtsc will fail with an error because it
tries to do string manipulation on the "flatModuleOutFile". This happens because
ngtsc only skips flat module indices if the option is set to "undefined".
Since this is not compatible with what was supported in ngc and such exceptions
should be avoided, the flat module check is now aligned with ngc.
```
TypeError: Cannot read property 'replace' of null
at Object.normalizeSeparators (/home/circleci/project/node_modules/@angular/compiler-cli/src/ngtsc/util/src/path.js:35:21)
at new NgtscProgram (/home/circleci/project/node_modules/@angular/compiler-cli/src/ngtsc/program.js:126:52)
```
Additionally setting the `flatModuleOutFile` option to an empty string
currently results in unexpected behavior. No errors is thrown, but the
flat module index file will be `.ts` (no file name; just extension).
This is now also fixed by treating an empty string similarly to
`null`.

Previously, ngtsc attempted to use the .d.ts schema for HTML elements to
check bindings to DOM properties. However, the TypeScript lib.dom.d.ts
schema does not perfectly align with the Angular DomElementSchemaRegistry,
and these inconsistencies would cause issues in apps. There is also the
concern of supporting both CUSTOM_ELEMENTS_SCHEMA and NO_ERRORS_SCHEMA which
would have been very difficult to do in the existing system.
With this commit, the DomElementSchemaRegistry is employed in ngtsc to check
bindings to the DOM. Previous work on producing template diagnostics is used
to support generation of this different kind of error with the same high
quality of error message.

This commit drops our custom, change-detection specific, equality comparison util
in favour of the standard Object.is which has desired semantics.
There are multiple advantages of this approach:
- less code to maintain on our end;
- avoid NaN checks if both values are equal;
- re-write NaN checks so we don't trigger V8 deoptimizations.
