cmdpal: Add "file" context items to the run items too (#40768)

After #39955, the "exe" items from the shell commands only ever have the
"Run{as admin, as other user}" commands. This adds the rest of the
"file" commands - copy path, open in explorer, etc.

This shuffles around some commands into the toolkit and common commands
project to make this easier.
