[AArch64] Enable AvoidLDAPUR for cpu=generic between armv8.4 and armv9.3. (#125261)
As added in #124274, CPUs in this range can suffer from performance
issues with ldapur. As the gain from ldar->ldapr is expected to be
greater than the minor gain from ldapr->ldapur, this opts to avoid the
instruction under the default -mcpu=generic when the -march is less that
armv8.8 / armv9.3.
I renamed AArch64Subtarget::Others to AArch64Subtarget::Generic to be
clearer what it means.
