Felix Arntz e5d1fca198 Themes: Fix block theme supports being added too early, leading to Customizer live preview bugs in 6.4.
The Customizer live preview broke because of [56635], however the root cause for the bug was a lower-level problem that had been present since WordPress 5.8: The block theme specific functions `_add_default_theme_supports()` and `wp_enable_block_templates()` were being hooked into the `setup_theme` action, which fires too early to initialize theme features. Because of that, theme functionality would be initialized before the current theme setup being completed. In the case of the Customizer, that includes overriding which theme is the current theme entirely, thus leading to an inconsistent experience.

This changeset fixes the bug by moving those two callbacks to the `after_setup_theme` action, which is the appropriate action to initialize theme features.
