ac/gpu_info: clamp gart_size_kb and vram_size_kb to fix buggy kernel driver 

amdgpu returns 12 TB of GTT on Kaveri, which resulted in 0 KB of GTT
after the conversion to uint32_t, which caused us to report 0 as the UBO
size, which disabled UBOs and downgraded the driver to OpenGL 3.0.

Fixes: aee8ee17a5 - radeonsi: change max TBO/SSBO sizes again and rework max alloc size
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/6642
