hwcontext_vulkan: temporarily disable formats which require shader+framework processing

Browse Source 
The main issue is that BGR formats only semi-exist in Vulkan. Unlike all
other formats, they require the user to manually remap the pixel order, and
are also forbidden from being written to without a format in shaders. The main
reason for this was conservative - Vulkan is supposed to work everywhere, including
platforms where there is no write-time remapping/swizzing support.
