rsx: Minor texture optimizations

[kd-11]

• Allow fast upload of data by looking for opportunities to upload the full data block in one go.
  Minor performance improvement noted when profiling a particularly problematic game (Split Second)
• Allow for auto-matching of pitch dimensions. Dumping statistics from games shows most use pitch alignment of 1 and there is no reason to force 256-byte alignment when uploading. Allows fast-copy to work which should make it easier on the GPU and CPU to handle. Also drastically lowers memory footprint of smaller textures.
• Batch compute and transfer operations when decoding texture data. Lowers overall number of compute invocations by an order of magnitude.

Didn't notice a perf diff in S/S. GFX are a little more broken. Guess the good news there is whatever you're doing IS impacting these specific gfx.

Performance seems good on GT5, but the rainbow textures are back:

But also getting after between a few seconds and a minute in the track:

F {RSX [0x0012080]} RSX: class std::runtime_error thrown: Verification failed (e=0x7f):
(in file C:\projects\rpcs3\rpcs3\Emu\RSX\VK\VKGSRender.cpp:3202)

Rainbow regression is fixed; the other crash is unrelated to this PR.

@kd-11 regression found with Top Spin 4 (cleared shader cache before testing)
vk only, OGL is not affected.

the Smurfs 2 - vulkan regression - playable > nothing. crashes at bootup

vk only, ogl not affected. the game requires libvdec.

@kd-11 as expected, Top Spin 3 has also regressed with this pr. vk only. ogl not affected

The regression is fixed by #6498
