Jonny Harris 9a734f3751 Themes: Improve performance of get_block_theme_folders function
This commit enhances the performance of the get_block_theme_folders function by introducing a new method called get_block_template_folders within the WP_Theme class. Previously, this function suffered from poor performance due to repeated file lookups using file_exists. The new method implements basic caching, storing the result in the theme's cache, similar to how block themes are cached in the block_theme property (see [55236]).

Additionally, this change improves error handling by checking if a theme exists before attempting to look up the file. It also enhances test coverage. 

Props spacedmonkey, thekt12, swissspidy, flixos90, costdev, mukesh27.
Fixes #58319.

The short version:

1. Create a clean MySQL database and user. DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.

2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.

3. $ svn up

4. Run the tests from the "trunk" directory:
   To execute a particular test:
      $ phpunit tests/phpunit/tests/test_case.php
   To execute all tests:
      $ phpunit

Notes:

Test cases live in the 'tests' subdirectory. All files in that directory will be included by default. Extend the WP_UnitTestCase class to ensure your test is run.

phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run. This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs. Pure unit tests may be used also, of course.

Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.

phpunit is intended to run at the command line, not via a web server.
