rspirv2 disassembly

[Firestar99]

We released rspirv2 🎉

• best reviewed commit by commit
• last commit "switch dis preset to default" has a ton of bless changes that don't need to be reviewed, since I'm only changing the disassembly settings for prettier disassembly
• rather, review the blesses in "replace disassembler*" where actual differences between rspirv and rspirv2 are visible
• while you're reviewing this, please also approve ci: split compiletest target-envs into steps #533

rspirv2 doesn't have its own traits here?

[Firestar99]

I assume you mean the function arg impl Assemble? That just needs to be rspirv's Assemble (can even drop Disassemble) to accept both rspirv's Module (compiletests with disassemble and disassemble-global) or Function (disassemble-function) as args. And turn those into bytes that rspirv2 can then "parse" (since it decodes on the fly, it doesn't actually parse it) and disassemble.

Color should be taken from the session context's --color value

[Firestar99]

Nope we can't. compiletest-rs would compare our output with ascii sequences to the *.stderr file without any, and fail every test. (Though it does print pretty colors while doing so :D )
