hwcontext_vulkan: enable read/write without storage

Browse Source 
BGR formats in Vulkan cannot be used in storage images, as the
pixel labels on storage images are always ordered as RGB, and
swizzling is not an option due to old hardware limitations.
This means that you must always use an RGB format and manually
swizzle when reading or writing to BGR images, or simply not use
a format in the shader itself.
This adds support for the latter.
