MdeModulePkg: Load the native Option ROM image if the native one exists
Issue:https://github.com/tianocore/edk2/issues/11800
If there are multiple Option ROM images existed, current code will load
the first image that the emulator supports. Usually, x86 ROM image is
the first one and non-x86 ROM image is behind x86 ROM image. When the
emulator is introduced, x86 ROM image instead of native image is loaded
on non-x86 platforms.
This patch introduces a mechanism to prioritize the loading of native
images. Firstly, search the native image. If the native one is found,
just finish the process since the goal is reached. Otherwise, search
the foriegn images that the platform may support.
