Rename (Ctrl+R, Ctrl+R) for X# symbols in Visual Studio, built on the Find All References engine (#2148).

What it does

• Renames the symbol under the cursor in the whole solution: methods, properties (ACCESS/ASSIGN pairs), fields, classes (all parts of a partial class), functions, locals and parameters. A method is renamed with its override family; a constructor call renames its class.
• Dialog: new name, "Include comments", "Include strings", "Include late-bound calls and symbols (:Name, #Name)" (members only, unchecked at the start of every rename), "Preview changes" (the VS Preview Changes dialog) and "Rename file" (when the file is named after the class).
• The search runs while the dialog is open; the dialog shows how many places change and how many are only reported.
• Files open in an editor window are changed in their buffer and stay unsaved. All other files are changed through an invisible editor and saved. One Ctrl+Z reverts everything; closed files are saved back after the undo.
• Places that may refer to the symbol but are not sure (late bound unless asked for, unresolved, ambiguous overload, inactive #ifdef code, files that could not be read) are never changed. After Apply they are listed in the Find All References window.
• Refused: interface members and their implementations, overrides of members declared in referenced assemblies (incl. System.Object members of classes without INHERIT), symbols not declared in the X# source.
• Checks the new name (keywords need @@), warns about existing symbols with the new name, and stops before any change when a closed file is read-only or a file changed since the search.

Changes outside the new Rename folder

• Find All References engine: search options (late bound, uncertain places, text in comments/strings/inactive code, transitive project scope), the uncertainty of each hit, its position in the file. The FAR command behaves as before.
• The FAR window handling moved from FindReferencesCommand to ReferencesWindow so that Rename can list its places there; it includes the keep fix of [VS] Find References: Keep Results no longer clears the kept window, search does not block the UI #2152.
• XFile.Rename(newPath) in the code model: after a file rename the open editor keeps its XFile; Rename moves it to the new path and parses the editor text. (A plain rename of an open, changed file in Solution Explorer still leaves the old class name in the code model until the file is saved; not changed here.)

Tests

• LanguageService.Tests: 106 tests (name check, guard, conflicts, planner, text and uncertainty of the engine).
• Checked in the VS 2022 experimental instance with a small test solution (method family + undo, overloads, ACCESS/ASSIGN, class + file rename and back, partial class, refusals, comments/strings, late-bound option, conflict warning, preview, read-only file) and with a large VO solution (39 changes in 13 files, search 2.4 s, apply 0.5 s, one Ctrl+Z restores all).
• VS 2019 project compiles.

Known limitations

• No inline rename (Roslyn only); the preview has no diff view.
• #Name literals of classes and functions are reported, not changed.
• Ctrl+Z does not rename the file back.
• No progress or cancel while the changes are applied (fast in practice).

Nice, although I would have preferred a XAML dialog window. That is also supported by VS2019
I do get an exception (that is captured) inside XSharpProjectTreePropertiesProvider.FindClassDeclaration() when I include the option "Rename File" because the original file cannot be found..

I will provide an PR with this
