Take advantage of some vk_sampler goodness and migrate all pvr
tex_formats to map to pipe_formats in pvr_formats.c. This allows us to
get rid of all the nasty manual packing functions.
This cleanup incidentally fixes some bad swizzling that was happening
in the manual handling.

Currently only the six vulkan 1.0 pre-defined formats are supported,
but some basic infrastructure that will be useful for implementing
VK_EXT_custom_border_color (and vulkan 1.1) is included.
Only formats currently listed in the pvr_format_table in pvr_formats.c
are currently supported. Unlike most (all?) other drivers, the PowerVR
hardware requires each entry in the border color table to be encoded
for every hardware format (of which there are 128 available, plus 128
for compressed formats).
Also in this commit:
- Two new constants in rogue_texstate.xml:
- IMAGE_WORD0_TEXFORMAT_MAX_SIZE, and
- SAMPLER_BORDERCOLOR_INDEX_MAX_SIZE; and
- A new device feature (tpu_border_colour_enhanced)
