[PATCH 5/7] WIP: efi: Add a test for the EFI bootmeth

[Simon Glass]

Add a simple test which checks that we can run an EFI app and that the

This is intended to catch the recent bootflow bug fixed by:

  20231115183522.1.I4cbfd34d576c0ad66a74c6ec3e8024adabc73573 at changeid/

TODO:
- change it to use USB instead of mmc
- drop the hacks in test.dts
