Support path pasting in terminal (#48222)

This adds the functionality to support pasting the file path of an item
when the copied item supports it. This mirrors the behavior of
`Terminal.app` on macOS.

This only implements the functionality on macOS but could be extended to
other platforms.

I find this convenient when I'm using Finder to navigate around the file
system and I want to copy a directory or file path and put it in the
terminal. You can copy the item from Finder and paste it into the
terminal and it will write out the full path of the item, making it easy
to change directories or provide path parameters to commands.

Release Notes:

- Added path pasting functionality in terminal
