media/gpu/vaapiWrapper: Add native pixmap validation

This CL introduces more rigorous validation for plane metadata when
populating VADRMPRIMESurfaceDescriptor:

- Verifying that plane pitch is at least the minimum required stride.
- Ensuring that the plane's memory range (offset + size) stays within
  the bounds of the DMA-buf.
