[X86] Support arch=x86-64{,-v2,-v3,-v4} for target_clones attribute
GCC 12 (https://gcc.gnu.org/PR101696) allows `arch=x86-64`
`arch=x86-64-v2` `arch=x86-64-v3` `arch=x86-64-v4` in the
target_clones function attribute. This patch ports the feature.
* Set KeyFeature to `x86-64{,-v2,-v3,-v4}` in `Processors[]`, to be used
by X86TargetInfo::multiVersionSortPriority
* builtins: change `__cpu_features2` to an array like libgcc. Define
`FEATURE_X86_64_{BASELINE,V2,V3,V4}` and depended ISA feature bits.
* CGBuiltin.cpp: update EmitX86CpuSupports to handle `arch=x86-64*`.
