* Add comprehensive performance analysis of UnitTests

Co-authored-by: tig <585482+tig@users.noreply.github.com>

* Migrate 2 Autocomplete tests and add Text tests analysis

Co-authored-by: tig <585482+tig@users.noreply.github.com>

* Add proof-of-concept: TextFormatter.Draw works in parallel tests with local driver

Co-authored-by: tig <585482+tig@users.noreply.github.com>

* Add CreateFakeDriver helper to ParallelizableBase and migrate 4 TextFormatterTests

Co-authored-by: tig <585482+tig@users.noreply.github.com>

* Remove proof-of-concept test from AutocompleteTests

Co-authored-by: tig <585482+tig@users.noreply.github.com>

* Move Scheme-accessing tests back to UnitTests to fix intermittent failures
