spirv: Add support for SpvCapabilityStorageImageWriteWithoutFormat
Allow that capability if the driver indicates that it is supported, and
flag whether images are read-only/write-only in the nir_variable (based
on the NonReadable and NonWritable decorations), which drivers may need
to implement this.
