Pull Request resolved: #9652 ## Context As title. Introduce a caching mechanism to store SPIR-V generated in a previous build to avoid re-compiling them. A shader will not be re-compiled if the source GLSL template is unchanged. For Meta internal builds, the `etvk.force_shader_rebuild` buck config can be used to force all shaders to be built without using the cache. ghstack-source-id: 274281888 @exported-using-ghexport Differential Revision: [D71916745](https://our.internmc.facebook.com/intern/diff/D71916745/)
