drm/amdgpu: grow VF RAS bad page table with bounded dynamic alloc

The VF RAS error handler used fixed-size bps[] / bps_bo[] arrays (512
slots). When the PF2VF bad-page block listed more entries than fit,
amdgpu_virt_ras_add_bps() could memcpy() past the end of those arrays.

Replace the fixed backing store with a dynamically grown table:
- Add capacity to track allocated slots separately from count.
- Start at 512 slots and realloc bps / bps_bo together when full.
- Refuse growth beyond maximum EEPROM record limit (AMDGPU_VIRT_RAS_BAD_PAGE_TABLE_MAX_CAPACITY).
- Return failure from amdgpu_virt_ras_add_bps() and stop processing
  the PF2VF block if allocation fails or the cap is reached.
