v3dv: create a v3dv_bo struct and reference it from v3dv_device_memory

So we have a lower level representation of a buffer object that we can
manipulate that is not tied to a Vulkan representation of memory. This
will be useful as we start allocating driver internal buffers, such as
command lists.

v3dv/debug: plug v3d_debug

Right now there is not a big reason/difference to implement the
utilities present at v3d_debug for the vulkan driver, so lets just
reuse it.

The other advantage is that is the debug utilities used by common

v3dv: implement vkCreateImage

This relies heavily in infrastructure taken from the v3d driver. We should
probably look for ways to share the code between both drivers by creating
a surface layout library that we can use from both, or at least moving
parts of the v3d driver to broadcom/common. Specifically:

We take v3d_tiling.c, which requires gallium's pipe_box type for some
helper functions that we don't quite need yet.

We copied and adapted bits of v3d_resource.c into v3dv_image.c, however,
it should be possible to look for ways to reuse the code instead of
duplicating it.

Pre-compute UIF padding into the slice setup. This is different from
what we do in v3d (we do this at cerate_surface time), but it is
more convenient for us to pre-calculate it here for all mipmap
slices.

if we want to make the file reusable and move the intel bits to

radv: Fix mipmap extent adjustment on GFX9+.

With arrays we really have to use the correct size for the base
mipmap to get the right array pitch. In particular, using
surf_pitch results in pitch that is bigger than the base mipmap
and hence results in wrong pitches computed by the HW.

It seems that on GFX9 this has mostly been hidden by the epitch
provided in the descriptor but this is not something we do on
GFX10 anymore.

Now this has some draw-backs:

1. normalized coordinates don't work
2. Bounds checking uses slightly bigger bounds.

2 mostly is not an issue as we still ensure that they're within
the texture memory and not overlapping other layers/mips, but
we can't properly ignore writes.

1 is kinda dead in the water ... On the other hand I'd argue that
using normalized coords & a filter for sampling a block view of
a compressed format is extraordinarily useless.

The old method we employed already had these drawbacks for everything
except the base miplevel of the imageview.

AFAICT this is the same tradeoff AMDVLK makes and no CTS test hits
this. (once it does I think the HW is dead in the water ... Only
workaround I can think of is shader processing which is hard because
we don't know texture formats at compile time.)

I also removed the extra calculations when the image has only 1 mip
level because they ended up being a no-op in that case.
