  [XRay][RISCV] RISCV support for XRay (#117368)

Add RISC-V support for XRay. The RV64 implementation has been tested in
both QEMU and in our hardware environment.

Currently this requires D and C extensions, but since both RV64GC and
RVA22/RVA23 are becoming mainstream, I don't think this requirement will
be a big problem.

Based on the previous work by @a-poduval :
