Clean up FAR aggregation (#48619)

* Clean up FAR and RenameLocations

This change had two goals:

1. Make the code easier to understand, primarily by simplifying the callback structure and minimizing side-effects
2. Improve performance by reducing repeated work, both FAR searches of individual projects and default tsconfig searches

This implementation attempts to preserve the merging order found in the original code (someone less relevant in the present state of using syntactic isDefinition).

* Stop enforcing search and aggregation order

...in preparation for implementing isDefinition explicitly.

Also restore convention of referring to `DocumentPosition`s as "locations".

* Introduce LanguageService.updateIsDefinitionOfReferencedSymbols

...to allow use of the checker when computing isDefinition across projects.

* Update baselines

* Tidy diff

* De-dup simplified results

* Baseline cross-project isDefinition results

* Move de-duping upstream to fix Full output

* Add server baseline test to confirm searches are not repeated

* Manually merge #48758

* Update baseline for newer fix to #48963
