Plugin: require minimum WordPress 6.2 (#53451)

* Initial commit

* Swapping `gutenberg_` functions for wp equivalents:
- wp_get_elements_class_name since 6.0.0
- _wp_get_presets_class_name since 6.2.0

Ensuring `build_query_vars_from_query_block` doesn't receive `gutenberg_` prefix during build

* - Remove compat/6.2 folder completely
- Add usages of wp_normalize_remote_block_pattern (since 6.2)

* - Using get_template_hierarchy (since 6.2)
- Removed tests already covered in Core

* Moving get_items() method from Gutenberg_REST_Block_Patterns_Controller_6_2 to Gutenberg_REST_Block_Patterns_Controller_6_3 because the following methods were updated in 6.3:

- gutenberg_load_remote_block_patterns
- gutenberg_load_remote_featured_patterns
- gutenberg_register_remote_theme_patterns

* Referencing private property

* Delete lib/compat/wordpress-6.3/class-gutenberg-rest-global-styles-controller-6-3.php because it wanted to live after a less than ideal rebase
