radv: ensure export arguments are always float

Browse source 
So that the signature is correct and consistent, the inputs to a export
intrinsic should always be 32-bit floats.

This and the previous commit fixes a large amount crashes from
dEQP-VK.spirv_assembly.instruction.graphics.16bit_storage.input_output_int_*
tests

Fixes: b722b29f10 ('radv: add support for 16bit input/output')
