[RISCV] Replace RISCV -> RISC-V in comments. NFC

[craig.topper]

Summary

To be consistent with RISC-V branding guidelines
https://riscv.org/about/risc-v-branding-guidelines/
Think we should be using RISC-V where possible.

More patches will follow.

[craig.topper]

Update RISCVISAInfo.* and RISCVTargetParser.*

[craig.topper]

Update a few more files.

LGTM.
