  [FMV][AArch64] Simplify version selection according to ACLE. (#121921)

Currently, the more features a version has, the higher its priority is.
We are changing ACLE https://github.com/ARM-software/acle/pull/370 as
follows:

"Among any two versions, the higher priority version is determined by
 identifying the highest priority feature that is specified in exactly
 one of the versions, and selecting that version."
