[spirv] nuke spirv-opt (#3877)

lots of AGILEism in spirv-opt
theres BETTER alternatives like https://github.com/renderbag/re-spirv (im not gonna bother for now, it probably has shitty build system)
it sucks

the IR already resolves most of the shader code to just constant load/stores
Spirv-opt passes do not seem to make such a big difference
only introduce extra latency
like for example cbuf pass in IR already removes a lot of code, that spirv_opt would otherwise miss due to the fact it doesn't have cbuf information
