Refactor the intermediate buffer copy path to use a generic callback
approach, making the code more maintainable and easier to extend with
new format conversions.
The core copy_intermediate() function is now format-agnostic, accepting
a conversion callback that handles the actual data transformation. This
moves format-specific logic (RGB<->RGBA conversion and ASTC
decompression) into dedicated callback functions, making the conversion
path explicit at each call site rather than hidden inside the copy
function.

Instead of allocating a buffer for the entire RGB->RGBA conversion
process. Just allocate a smaller buffer that is the size of a tile and
do the conversion one tile at a time.

The needs_temp_copy() function was incorrectly identifying some
depth/stencil formats as needing RGB<->RGBA conversion.
VK_FORMAT_D32_SFLOAT_S8_UINT maps to PIPE_FORMAT_Z32_FLOAT_S8X24_UINT,
which has 3 channels (F32 depth, UP8 stencil, X24 padding). The
component count check (== 3) was matching this as an RGB color format,
causing depth/stencil images to incorrectly use the RGB conversion path.
Add an explicit vk_format_is_depth_or_stencil() check before the
component count test to ensure depth/stencil formats always use the
direct copy path.

The intermediate buffer between the 2 images is linear, its stride
should be a function of the tile's logical width.
Normally this should map to the values reported by ISL except for
TileW where for some reason it was decided to report 128 for TileW
instead of the actual 64 size (see isl_tiling_get_info() ISL_TILING_W
case)

For 3-component RGB images with OPTIMAL tiling, we need to create the
surface as RGBX or RGBA. When a host image copy to/from this image
happens, we calculate sizes and offsets based on the 4-component surface
and blow past the end of the 3-component API provided buffer.
Hilarity^WSegfault ensues.
Ideally we'd calculate the right sizes and have the tiled copy functions
handle the conversion, but they are format unaware and expect to just
copy bytes in blocks of equal sizes from both sides.
Handle this case by making an intermediate copy to/from linear RGB
from/to linear RGBX, and pass that intermediate slice to the tiled copy
functions.

Per VUID-VkCopyImageToImageInfo-srcImage-09069,
srcImage and dstImage must have been created with identical image
creation parameters, so we are not going to have copies from color <->
depth/stencil, but we can copy both D/S aspects of an image at the same
time.
Nothing says that we can't copy from one plane of a multiplanar image to
another, so handle that case too (though nothing is currently testing
it).
