drm/amdgpu: Modify indirect buffer packages for resubmission
When the preempted IB frame resubmitted to cp, we need to modify the frame
data including:
1. set PRE_RESUME 1 in CONTEXT_CONTROL.
2. use meta data(DE and CE) read from CSA in WRITE_DATA.
Add functions to save the location the first time IBs emitted and callback
to patch the package when resubmission happens.
