video_core: Account of runtime state changes when compiling shaders (#575)

* video_core: Compile shader permutations

* spirv: Only specific storage image format for atomics

* ir: Avoid cube coord patching for storage image

* spirv: Fix default attributes

* data_share: Add more instructions

* video_core: Query storage flag with runtime state

* kernel: Use std::list for semaphore

* video_core: Use texture buffers for untyped format load/store

* buffer_cache: Limit view usage

* vk_pipeline_cache: Fix invalid iterator

* image_view: Reduce log spam when alpha=1 in storage swizzle

* video_core: More features and proper spirv feature detection

* video_core: Attempt no2 for specialization

* spirv: Remove conflict

* vk_shader_cache: Small cleanup
