Add a Vulkan feature to compress float32 vertex formats. Use the vertex conversion pipeline in VertexArrayVk to detect static vertex data and convert float32 vertices to float16. This feature is useful for determining if an allication is vertex bandwidth bound and seeing what gains could be had by using smaller attributes. This feature could be implemented in ANGLE's frontend but new infrastructure for converting and storing the converted attributes would need to be added to gl::VertexArray. Our backends already have the functionality needed to handle unsupported attribute formats and this can be repurposed for compressing vertex formats.
