Update Metal argument buffer resource usage in Metal command encoder.
MVKPipeline track descriptors used by shaders. Update resources as dirty at start of Metal render pass or compute encoder. Add MVKCommandEncoder::beginMetalComputeEncoding() to mark a new Metal compute encoder. MVKResourcesCommandEncoderState track resource usage that needs to be encoded. Add MVKResourcesCommandEncoderState::encodeArgumentBufferResourceUsage(). Add MVKCommandEncoderState::beginMetalComputeEncoding() to mark compute state dirty when a MTLComputeEncoder is created. Add SPIRVToMSLConversionConfiguration::isResourceUsed(). MVKBitArray add ability to retain contents when resizing, and clear bit during getBit(). Add MVKBitArray getBit() option to clear bit.
