Resolves

Fixes #8005

Proposed Changes

Makes it so that context menu options can be registered to apply to workspace comments. To support one option that creates a workspace comments at the click position, I also had to pass the original right click event to all of the callbacks.

Also upgrades the old workspace comments context menu options to work with the "new" (several years old at this point :P ) context menu system.

Test Coverage

Manually tested that context menu options work.

Breaking changes / To fix

Removes the commentDuplicate, commentDelete, and workspaceCommentOption exports from Blockly.ContextMenu. Instead you can call registerCommentDuplicate, registerCommentDelete, and registerCommentCreate on Blockly.ContextMenuItems respectively. Note that these don't return LegacyContextMenuOption objects. Instead they register the context menu options as a side effect using the non-legacy system.

You can also call Blockly.ContextMenuItems.registerCommentOptions to register all three options at once.
