Themes: Improve performance of _add_block_template_part_area_info and _add_block_template_info functions.

Improve performance of `_add_block_template_part_area_info` and `_add_block_template_info` function by passing the `with_supports` parameter to the `WP_Theme_JSON_Resolver::get_theme_data` method. This results in hitting an existing cache and in many less calls to get_option. 

Props spacedmonkey, flixos90, SergeyBiryukov, peterwilsoncc, desrosj.
Fixes #57077.
