VSCode only de-duplicates references results for "go to references" requests
but does not de-duplicate them for "find all references" requests. The
result is that users see duplicate references for results in TypeScript
files - one from the built-in TS extension and one from us.
While this is an issue in VSCode (see https://github.com/microsoft/vscode/issues/117095)
this commit provides a quick workaround on our end until it can be addressed there.
This commit should be reverted when microsoft/vscode/issues/117095 is resolved.

Rather than mutating the span on the template when renaming literal strings,
this commit updates the logic to mutate the `TextSpan` equivalent that
is used by the Language Service.
PR Close#40484
The initial implementation assumed that the consuming editors would
de-duplicate rename locations. In fact, vscode treats overlapping rename
locations as distinct and errors when trying to preview the renames.
This commit updates the language service to de-duplicate exact file+span
matches before returning rename and reference locations.
While vscode _does_ de-duplicate reference results, it still makes sense
to de-duplicate them on our side when possible to make tests more
understandable. If a template has 3 instances of a variable, it makes
sense to get get 3 reference results rather than 4+ with some duplicates.

The `getRenameInfo` action is used by consumers to
1. Determine if a location is a candidate for renames
2. Determine what text to use as the starting point for the rename
PR Close#40439
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.

Rather than expecting that a position in a template only targets a
single node, this commit simply adjusts the approach to account for two way
bindings. Specifically, we attempt to get references for each targeted
node and then return the combination of all results, or `undefined` if
none of the target nodes had references.
PR Close#40185
Given the template
`<div (click)="doSomething($event)"></div>`
If you request references for the `$event`, the results include both `$event` and `(click)="doSomething($event)"`.
This happens because in the TCB, `$event` is passed to the `subscribe`/`addEventListener`
function as an argument. So when we ask typescript to give us the references, we
get the result from the usage in the subscribe body as well as the one passed in as an argument.
This commit adds an identifier to the `$event` parameter in the TCB so
that the result returned from `getReferencesAtPosition` can be
identified and filtered out.

The TCB utility functions used to find nodes in the TCB are currently
configured to ignore results when an ignore marker is found. However,
these ignore markers are only meant to affect diagnostics requests. The
Language Service may have a need to find nodes with diagnostic ignore
markers. The most common example of this would be finding references for
generic directives. The reference appears to the generic directive's
class appears on the type ctor in the TCB, which is ignored for
diagnostic purposes.
These functions should only skip results when the request is in the
context of a larger request for _diagnostics_. In all other cases, we
should get matches, even if a diagnostic ignore marker is encountered.

This commit adds the ability to find references for a directive or component
from within a component template. That is, you can find component references
from the element tag `<my-c|omp></my-comp>` (where `|` is the cursor position)
as well as find references for directives that match a given attribute
`<div d|ir></div>`.
PR Close#40054
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.
