gpu: pvr: dump render status buffers during SGX HW recovery

To aid debugging, dump any status buffers that are provided by the
ogles user space library for the rendering context that was active
at the time of recovery. At the moment the USSE final patched
versions of vertex and fragment shaders that were bound within the
frame causing the HWRec are provided, but later on more types can be
added.
