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.

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.

This commit adds "find references" functionality to the Ivy integrated
language service. The basic approach is as follows:
1. Generate shims for all files to ensure we find references in shims
throughout the entire program
2. Determine if the position for the reference request is within a
template.
* Yes, it is in a template: Find which node in the template AST the
position refers to. Then find the position in the shim file for that
template node. Pass the shim file and position in the shim file along
to step 3.
* No, the request for references was made outside a template: Forward
the file and position to step 3.
3. (`getReferencesAtTypescriptPosition`): Call the native TypeScript LS
`getReferencesAtPosition`. For each reference that is in a shim file, map those
back to a template location, otherwise return it as-is.

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).
