Nathan Gauër 35d8b05de4 opt: add capability trimming pass (not default). (#5278) ... This commit adds a new optimization which tries to remove unnecessary capabilities from a SPIR-V module. When compiling a SPIR-V module, you may have some dead-code using features gated by a capability. DCE will remove this code, but the capability will remain. This means your module would still require some capability, even if it doesn't require it. Calling this pass on your module would remove obsolete capabilities. This pass wouldn't be enabled by default, and would only be usable from the API (at least for now). NOTE: this commit only adds the basic skeleton/structure, and doesn't mark as supported many capabilities it could support. I'll add them as supported as I write tests.
