buffer_cache: allow 32 storage buffers per stage

Native Switch 2 compute shaders (such as Donkey Kong Bananza) bind up to 18 global memory ranges, causing out-of-bounds binding errors:
  HW.GPU <Error> buffer_cache.h:BindComputeStorageBuffer: Storage buffer index 16 exceeds maximum storage buffer count
  HW.GPU <Error> buffer_cache.h:BindComputeStorageBuffer: Storage buffer index 17 exceeds maximum storage buffer count
followed by GPU driver access violations (0xc0000005).

The enabled and written storage buffer bitmasks (enabled_compute_storage_buffers and written_compute_storage_buffers) are already u32, so widening NUM_STORAGE_BUFFERS from 16 to 32 fits naturally within the existing 32-bit masks.
