[RISCV] Update B extension version to 0.93.

[asb]

I don't think any of the other patches in the stack update the comment at the top of RISCVInstrInfoB.td to say "version 0.92" rather than "version 0.93", and this is probably a reasonable patch to do it in.

[craig.topper]

Update header on RISCVInstrInfoB.td

[craig.topper]

Rebase after clang-format in Zba patch

[craig.topper]

Remove conflict marker that got left behind

This might need updated. The statement is still true in 0.92, but it's not the "current version"

[craig.topper]

Remove reference to version from the rori comment. The version doesn't really matter, I doubt the encoding will ever be added.
