aarch64: Remove FMV features whose names may change

Some architecture features have been combined under a single command
line flag, but have been assigned multiple FMV feature names with the
command line flag name enabling only a subset of these features in
the FMV specification.  I've proposed reallocating names in the FMV
specification to match the command line flags [1], but for GCC 14 we'll
just remove them from the FMV feature list.

gcc/ChangeLog:

	* config/aarch64/aarch64-option-extensions.def:
	Remove "memtag", "memtag2", "ssbs", "ssbs2", "ls64", "ls64_v"
	and "ls64_accdata" FMV features.
