[RISCV] Add codegen support for ri.vinsert.v.x and ri.vextract.x.v (#136708)
These instructions are included in XRivosVisni. They perform a scalar
insert into a vector (with a potentially non-zero index) and a scalar
extract from a vector (with a potentially non-zero index) respectively.
They're very analogous to vmv.s.x and vmv.x.s respectively.
The instructions do have a couple restrictions:
1) Only constant indices are supported w/a uimm5 format.
2) There are no FP variants.
One important property of these instructions is that their throughput
and latency are expected to be LMUL independent.
