[RISCV][Clang][TargetParser] Support getting feature unaligned-scalar-mem from mcpu. (#71513)
This patch reference ac1ffd3caca12c254e0b8c847aa8ce8e51b6cfbf to suppot
a soft coding way to identify whether a cpu has a feature
`unaligned-scalar-mem` by `RISCVProcessors.td`.
This patch does not provide test case since there is no risc-v cpu
support `unaligned-scalar-mem` in llvm upstream now.
