Karmjit Mahil fad7e858f2 pvr: Extend hard coding infra to allow per stage per device coding.
This commit extends the graphics hard coding infrastructure to
allow the independent hard coding of stages, i.e. hard code fragment
stage and vertex stage separately instead of having to hard code
everything.

It also extends the infrastructure to allow per device hard coding.

Karmjit Mahil e5439bf4aa pvr: Add stricter type checking in pvr_csb_pack().
Since the packing functions generated by csbgen use a void pointer
for the buffer in which to pack, it's possible to easily write out
of bounds. This commits attempts to reduce the chances by
having the pack macro check that the pointer passed points to an
element sized equally to the state word being packed. Catching
these errors earlier.

As can be seen in this commit, there already was a case of this:
"pds_ctrl". The word size is meant to be 64 bits but the pointer
was pointing to a 32 bit field.

Although it's fine for the word size to be smaller than the
storage pointed to by the pointer, this is not allowed just to
be extra careful.

Karmjit Mahil 0d25db406b pvr: Fix seg fault in vkAllocateDescriptorSets().
In cases when no immutable samplers were present but sampler
descriptor set layout bindings were, a seg fault was being caused
by an attempt to get the immutable sampler from within the
immutable sampler array while the array was not allocated.

This commit also remove the binding type check since only those
specific types can have immutable samplers. The check is covered
by the descriptor set layout creation and assignment of
has_immutable_samplers.

This commit also makes the immutable samplers const, since they're
meant to be immutable.

This commit also adds has_immutable_samplers field to descriptor
set layout. Previously to check whether immutable
samplers were present or not you'd check for the layout binding's
descriptor count to be 0 and the immutable sampler offset to be 0.
This doesn't tell you everything. If you have a descriptor of the
appropriate type (VK_DESCRIPTOR_TYPE_{COMBINED_,}IMAGE_SAMPLER).
So descriptor count of >1. The offset can be 0 if you don't have
immutable sampler, or have them at the beginning of the immutable
samplers array. So you can't determine if you really have immutable
samplers or not. One could attempt to perform a NULL check on the
array but this would not work in cases where you have following set
layout bindings with immutable samplers as the array stores the
whole layout's immutable samplers.
