Themes: Improve the performance of _get_block_templates_paths.

This avoids redundant recursive lookups for block template paths in the same base directory by implementing a static cache. It also replaces an potentially expensive `file_exists` call in favor of doing recursive iteration of files inside a try/catch block. 

Props thekt12, spacedmonkey, flixos90, mukesh27, joemcgill.
Fixes #58196.
