feat(ui): adds support for copy pasting complex fields

[akhrarovsaid]

What?

This PR introduces support for copy + pasting complex fields such as Arrays and Blocks. These changes introduce a new ClipboardAction component that houses logic for copy + pasting to and from the clipboard to supported fields. I've scoped this PR to include only Blocks & Arrays, however the structure of the components introduced lend themselves to be easily extended to other field types. I've limited the scope because there may be design & functional blockers that make it unclear how to add actions to particular fields.

Supported fields:

• Arrays (Demo)
  • Array Rows (Demo)
• Blocks (Demo)
  • Block Rows (Demo)

Fields that may be supported in the future with minimal effort by adopting the changes introduced here:

• Tabs
• Groups
• Collapsible
• Relationships

This PR also encompasses e2e tests that check both field and row-level copy/pasting.

Why?

To make it simpler and faster to copy complex fields over between documents and rows within those docs.

How?

Introduces a new ClipboardAction component with helper utilities to aid in copy/pasting and validating field data.

Addresses #2977 & #10703

Notes:

• There seems to be an issue with Blocks & Arrays that contain RichText fields where the RichText field dissappears from the dom upon replacing form state. These fields are resurfaced after either saving the data or dragging/dropping the row containing them.
• Copying a Row and then pasting it at the field-level will overwrite the field to include only that one row. This is intended however can be changed if requested.
• Clipboard permissions are required to use this feature. See Clipboard API caniuse.
