add CLI flag to disable optimizer

[charles-cooper]

What I did

Fix #2516

How I did it

Add no-optimize flag, thread through the codebase and disable LLL+assembly optimizations

How to verify it

Build, compile something with vyper --no-optimize -f ir foo.vy and vyper --no-optimize -f asm foo.vy and see the difference.

Description for the changelog

Add --no-optimize flag to the CLI

also, should probably run the test suite with this flag active and inactive, and (almost) all tests should pass

@fubuloubu got the optimization parameter working as a command line flag, and added several more workflow actions to test. we might want to add as a required test
