RISC-V: Add T-Head SYNC 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 XTheadSync extension, a collection of
T-Head-specific multi-processor synchronization instructions.
The 'th' prefix and the "XTheadSync" extension are documented in a PR
for the RISC-V toolchain conventions ([1]).
