pvr: pvr_pds_fragment_program_create fix allocation callback usage

The staging buffer is persistent until the destruction of the pvr_pipeline
object, so we should set the allocation scope to PVR_ALLOC_SCOPE_OBJECT instead
of PVR_ALLOC_SCOPE_COMMAND.

Also did the same change in the function pvr_pds_coeff_program_create_and_upload
for the staging buffer, because that buffer is also destroyed at pipeline destruction.

Fixes dEQP-VK.api.object_management.single_alloc_callbacks.graphics_pipeline.
