Adds additional modes to the Renamer for renaming just HLSL or MSL keywords. The sanitizers no longer rename reserved keywords automatically, which isn't usually necessary anyway since Dawn renames all symbols. The tint executable automatically renames reserved keywords when targeting HLSL and MSL. It now also has an option to rename everything, which is useful for testing the renamer.
