mach: Make `./mach try` a little friendlier (#31290)

1. Move `./mach try` to `testing_commands.py which is a bit more
   consistent.
2. Make `./mach try` print out the remote name always and properly
   form the URL for ssh repositories.
3. Print out the try configuration matrix to make it more obvious
   what is being triggered remotely.
4. Better error handling. Print and error and exit if the remote isn't
   on GitHub and also clean up properly if something fails after making
   the temporary commit.
