[Bug 2122288] [NEW] Lack of proper handling of new firmware architectures
Public bug reported:
Description
===========
Recent CentOS and Fedora introduced a few new architecture patterns of OVMF firmware.
However current nova does not handle these patterns appropriately and assumes that every firmware is always "statefull" and also "plush" type.
1) mode=stateless
example. 60-edk2-ovmf-x64-amdsev.json in Fedora 40

These files should be excluded when detecting the loader files, to avoid
KeyError or launch time error.
