panfrost: Implement native RECT textures

We started honouring the normalized_coords flag in the texture
descriptor, but a bisection revealed that broke RECT textures -- since
we were *also* lowering them in the shader. So just remove the
shader-based lowering, use native RECT textures, and enjoy the nominal
reduction in complexity and performance boost.

Fixes: 3e47a1181b7 ("panfrost: Add MALI_SAMP_NORM_COORDS flag")
