vulkan: always enable ReadWithoutFormat/WriteWithoutFormat

Browse Source 
This implements support for reading and writing storage images with
no format.
The issue is that we define our images as arrays, and arrays can
only have a single type, which means that f.ex. NV12 needs two
different images, R8 and RG8.

The only driver known not to advertise support for the extension
as a whole is Intel, because they have parial support for odd formats
we never use. Therefore, just always enable it by default.
