vc4: Rewrite T image handling based on calling the LT handler.
The T images are composed of effectively swizzled-around blocks of LT (4x4
utile) images, so we can reduce the t_utile_address() calls by 16x by
calling into the simpler LT loop.
This also adds support for calling down with non-utile-aligned
coordinates, which will be part of lifting the utile alignment requirement
on our callers and avoiding the RMW on non-utile-aligned stores.
Improves 1024x1024 TexSubImage by 2.55014% +/- 1.18584% (n=46)
Improves 1024x1024 GetTexImage by 2.242% +/- 0.880954% (n=32)
