zink: clamped maxPerStageDescriptorUniformBuffers limits to INT_MAX when stored as uint32_t.

This stops issues if a driver returns a value that is greater than a signed int.
Also make it match many of the other limit versions conversions.
Seen on Radeon drivers, IIRC. gpuinfo.org also reports many GPUs returning 4GB values.
