RISC-V: Add T-Head MAC 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 XTheadMac extension, a collection of
T-Head-specific multiply-accumulate instructions.
The 'th' prefix and the "XTheadMac" extension are documented
in a PR for the RISC-V toolchain conventions ([1]).
