[FMV][AArch64] Don't optimize backward compatible features in resolver. (#90928)

For arch64 features, such as Branch Target Identification or MTE (Memory
Tagging Extension), compatible with targets that lack their support we
may encounter scenarios where a binary compiled with MTE for example is
executed on both MTE and non-MTE hardware and we still need to detect at
runtime whether the MTE feature is available to choose the appropriate
function version.
So, we cannot optimize the function multi versioning resolver by
removing checks for these features enabled for the target during
compilation.
