Do this by removing the compatibility table and only using hard coded shaders
when present. The hard coded shaders, along with the hard coding framework
itself, can be dropped once the compiler is capable of compiling the hard coded
shaders. In the meantime we don't want to risk regressing things that we know
work because we temporarily can't test them.
This restriction is being dropped now as the new compiler framework has been
merged and we want to make use of it so it can be developed further.

This is based on the new approach of having a descriptor set
addresses table in memory. To handle dynamic offsets provided on
vkCmdBindDescriptorSets() we duplicate the set with dynamic
descriptors, apply the offsets, and write the new bo's address
into the table. There are better ways of handling dynamic
descriptors but this implementation won't require many/if any
changes in the compiler code.
The descriptor set itself doesn't allocate and reserve space for
the dynamic descriptors since they would all be collected together
when creating the pipeline layout. While copying the descriptor
set we allocate extra space at the end for the dynamic primaries
and secondaries to account for that.

For pvr_setup_descriptor_mappings_new() there will be quite a few
variables of which the value depend on the stage so rather than
having all that selection in the `switch` at the beginning of the
function the helper macro provides a compact selection in the
desired scope.

Previously UBOs and various buffers, as well as the native
descriptor sets were DMAed into the shared registers. This added
complexity in allocating the registers and various other places.
We also ended up being in situations were we wouldn't know the size
of a buffer by the time the shaders were being compiled. It would
be possible to determine the size by inspecting the shader but
that would introduce more complexity in the compiler.
To get things working sooner, avoid extra complexity for
now, a different approach was devised.
The driver will write the addresses of the currently bound
descriptor sets into a device buffer. The device buffer is referred
to as the descriptor set addrs table. The dev addr of the table is
written into a shared register. To access the buffers the shader
will first get the address of the descriptor set from the in memory
table. Then get the primary descriptor from the descriptor set. And
finally access the in memory buffer with the address it read from
the descriptor. Essentially there's three level of indirection and
all the buffers are in memory. The shader will know what offset the
primary descriptor is located based on the descriptor set layout.
The descriptor set address could have been written into the shareds
directly but that would require extra handling on the compiler side
so opted to just write the table address instead.

This commit sets up the infrastructure to introduce the new
descriptor set approach while keeping the old paths so the
hard coded apps are still operational. The old paths will be
removed once the compiler can compiler shaders for those apps
and the driver-compiler interface is fully flushed out.

The hardware requires depth/stencil attachments to be size-aligned to
the zls tile size (as defined by rogue_get_zls_tile_size_xy()).
In practice however, this is a tiny edge case. The restriction only
applies during some operations, and any attachment larger than the tile
size will be twiddled and over-allocated into alignment beforehand.
This commit also adds the mentioned rogue_get_zls_tile_size_xy()
function. These values differ from the regular tile_size_{x,y} feature
values in some cases. Instead of including them as features as well, we
compute them directly.
