- Renamed `RazorEditorParser` => `VisualStudioRazorParser` (maintained a copy of the original in Legacy)
- Tried to make as little changes as possible to the `BackgroundParser` due to its complexity; mostly just removed the TreeStructureChanged logic since this is re-done on the Razor editor side of things.
- Split the `RazorEditorParserTest`s into two separate tests. Partial parser tests and the VS parsing tests.
- Updated `StringTextSnapshot` to support changes in order to test the VS parser.
#1536
- Revived `RazorEditorParser`.
- Made `PartialParseResult` internal and renamed it to `PartialParseResultInternal`. This fell in line with other syntax tree types.
- Moved the `RazorEditorParser` implementation away from `TextChange` and `ITextBuffer`. Instead it now relies on `SourceChange` and the VS contract `ITextSnapshot`.
- Added `RazorEditorParserTest` to ensure the changes in implementation did not impact previous functionality.
- Removed some obvious tests that unnecessarily re-tested behavior that was already verified.
- Updated tests.
- Moved several Language.Test types to the common test project so they could be reused.
