Invert component names in RG11B10 and RGB10A2

Browse Source 
The CL that introduced this formats reordered their components based on
the name of the Vulkan formats, but it turns out that WebGPU lists
components from low bits to high-bits while Vulkan PACK32 formats are
listed from high to low. So the format component orders match, except
for RGB10A2 which is actually BGR10A2 in Vulkan. Instead the Vulkan
backend is updated to correctly use the RGB10A2 format.
