Convert Hooks to Object Oriented Implementation

Did basic regression testing on both D10 and D11, primarily focusing on usage tracking.

Everything looks good to me.

Scenarios covered:

• Adding PatternKit blocks as well as WebRH blocks.
• Updating and removing blocks.
• Performing actions from both the new window and within Layout Builder.
• Adding translations and verifying in the PatternKit usage report.
• Validating CKEditor5 behavior.
• Tested with different icons (other than “none”) from /admin/config/user-interface/patternkit/json.
• Validated entry for each patternkit block on each page is listed on the admin reports page at /admin/reports/pattern-usage

Each entry displays the following:

• The page title
• A link to the page
• The name of the used pattern
• A path to the pattern within the layout
• The language of the revision containing the pattern entry
• The node ID of the node layout
• The revision ID of the node revision

Also, I have validated the values for each of the entry - Name of the pattern, format of layout path with different section index value, nested pattern, revision id, node id. All the values are accurate.

• Edit an existing page to add or remove blocks and expect this change to be reflected in the usage report without rescanning via the drush command.
• Create a new page and set block content on the layout. Expect the new results to be reflected in the usage report without rescanning via the drush command.

Confirmed and ready for merge and inclusion in the 9.1.2 release.
