[Feature] CMake Language Services - Colorization - Add all built-in variables and properties

### Request Overview

Our textmate grammar for language services colorization doesn't have all variables and properties included right now. We need to update the grammar to include them all.

### Additional Information

_No response_

Start by locating the TextMate grammar used for CMake language-services colorization and identify how variables and properties are currently listed. Compare those entries with the complete CMake built-in variable and property lists, then verify that all requested names receive the intended colorization.
