Stabilize Ratified RISC-V Target Features

Browse source 
As shortly discussed on Zulip
(394793704),
this commit stabilizes the ratified RISC-V instruction bases and
extensions.

Specifically, this commit stabilizes the:
* Atomic Instructions (A) on v2.0
* Compressed Instructions (C) on v2.0
* Integer Multiplication and Division (M) on v2.0
* Bit Manipulations (B) on v1.0 listed as `zba`, `zbc`, `zbs`
* Scalar Cryptography (Zk) v1.0.1 listed as `zk`, `zkn`, `zknd`, `zkne`, `zknh`, `zkr`, `zks`, `zksed`, `zksh`, `zkt`, `zbkb`, `zbkc` `zkbx`
