RISC-V: Add T-Head MemPair vendor extension
T-Head has a range of vendor-specific instructions.
Therefore it makes sense to group them into smaller chunks
in form of vendor extensions.
This patch adds the XTheadMemPair extension, a collection of T-Head specific
two-GP-register memory operations.
The 'th' prefix and the "XTheadMemPair" extension are documented in a PR
for the RISC-V toolchain conventions ([1]).
