This makes the apps/*.efi files available for download and testing after each build.
Also clean up the GitHub Actions workflows a little bit.

To builds the apps with MinGW, the CRT0 library must be ignored because
it is ELF specific and we don't need to go through ELF relocations.
We also apply the GNU_EFI_USE_MS_ABI (since we have it), remove the -z
flags, that are invalid in MinGW, and clean up the apps Makefile.
Note that setjump and debughook are excluded from MinGW builds as they
use constructs that are not available there.
