Detailed Description of the Pull Request / Additional comments

• Paste actions now have their text and Ctrl+Num shortcut correctly read out by screen readers.
• Paste actions now work with keyboard navigation (arrow keys, enter, space).
• The following items now also work correctly with screen readers:
  • Clipboard history items (including images)
  • Clipboard history more options button
  • Thumbs up/down buttons
• Many other extra description texts have been provided which do not seem to have functional impact when using Narrator in default mode, but will possibly improve descriptions in higher verbosity settings.
• Paste Formats now use a PasteFormatTemplateSelector that more explicitly indicates disabled items.

Validation Steps Performed

Tested changes using Narrator (default settings) and performed a sanity check.
