This commit lays the groundwork for potentially providing rename
locations from the Ivy native LS. The approach is very similar to what
was done with the feature to find references. One difference, however,
is that we did not require the references to be fully "correct". That
is, the exact text spans did not matter so much, as long as we provide a
location that logically includes the referenced item.
An example of a necessary difference between rename locations and references is
directives. The entire element in the template is a "reference" of the
directive's class. However, it's not a valid location to be renamed. The
same goes for aliased inputs/outputs. The locations in the template
directly map to the class property, which is correct for references, but
would not be correct for rename locations, which should instead map to
the string node fo the alias.
As an initial approach to address the aforementioned issues with rename
locations, we check that all the rename location nodes have the same text. If
_any_ node has text that differs from the request, we do not return any
rename locations. This works as a way to prevent renames that could
break the the program by missing some required nodes in the rename action, but
allowing other nodes to be renamed.

This commit ensures that the template type checker returns symbols for
all outputs if a template output listener binds to more than one.
PR Close#40144
When `checkTypeOfPipes` is set to `false`, the configuration is meant to
ignore the signature of the pipe's `transform` method for diagnostics.
However, we still should produce some information about the pipe for the
`TemplateTypeChecker`. This change refactors the returned symbol for
pipes so that it also includes information about the pipe's class
instance as it appears in the TCB.

In preparation for in-memory testing infrastructure, the existing Ivy
language service tests are moved to a `legacy` directory. These existing
tests rely on a single integration project in `test/project/app`, which
presents a number of challenges:
* adding extra fields/properties to the integration project for one test
can cause others to fail/flake.
* it's especially difficult to test any cases that require introducing
intentional errors, as those tend to break other tests.
* tests load files from disk, which is slower.
* tests rely on the real built versions of @angular/core and
@angular/common, which makes them both slow to build and require rebuilds
on every compiler change.
* tests share a single tsconfig.json, making it extremely difficult to test
how the language service handles different configuration scenarios (e.g.
different type-checking flags).

Similar to #39613, #39609, and #38898, we should store the `keySpan` for
Reference nodes so that we can accurately map from a template node to a
span in the original file. This is most notably an issue at the moment
for directive references `#ref="exportAs"`. The current behavior for the
language service when requesting information for the reference
is that it will return a text span that results in
highlighting the entire source when it should only highlight "ref" (test
added for this case as well).
PR Close#39616
Though we currently have the knowledge of where the `key` for an
event binding appears during parsing, we do not propagate this
information to the output AST. This means that once we produce the
template AST, we have no way of mapping a template position to the key
span alone. The best we can currently do is map back to the
`sourceSpan`. This presents problems downstream, specifically for the
language service, where we cannot provide correct information about a
position in a template because the AST is not granular enough.
This is essentially identical to the change from #38898, but for event
bindings rather than input bindings.

Rather than re-reading component metadata that was already interpreted
by the Ivy compiler, the Language Service should instead use the
compiler APIs to get information it needs about the metadata.

Test harness `setup()` is expensive, in the order of ~2.5 seconds.
We could speed up `fit()` tests considerably if `setup()` is wrapped
in `beforeAll()` to avoid running it unnecessarily.

This commit enables the Ivy Language Service to 'go to definition' of a
templateUrl or styleUrl, which would jump to the template/style file
itself.
PR Close#39202
When an input name is part of the directive selector, it would be good to return the directive as well
when performing 'go to definition' or 'go to type definition'. As an example, this would allow
'go to type definition' for ngIf to take the user to the NgIf directive.
'Go to type definition' would otherwise return no results because the
input is a generic type. This would also be the case for all primitive
input types.
PR Close#39243
For directives/components, it would be generally more appropriate for
"go to type definition" to be the function which navigates to the class
definition. However, for a better user experience, we should do this
for "go to definition" as well.
