drm/xe/xe2: Update render/compute context image sizes
The render and compute context are significantly smaller on Xe2 than on
previous platforms.
Registers:
- Render: 3008 dwords -> 12032 bytes -> round to 3 pages
- Compute: 1424 dwords -> 5696 bytes -> round to 2 pages
We also allocate one additional page for the HWSP, so the total
allocation sizes for render and compute are 4 and 3 pages respectively.
Bspec: 65182, 56578, 55793
