update codec config after svc/scale controls

This ensures the encoder state/allocations stay in sync with scaling and
svc layer changes. In the SVC case, depending on the resolution,
differences in the chosen superblock size among layers may have caused a
crash. This was reproducible in WebRTC in screen content mode.

The fix is based on a change by Yuan Tong (tongyuan200097) [1]. It
refreshes the encoder config after AOME_SET_SCALEMODE,
AOME_SET_NUMBER_SPATIAL_LAYERS and AV1E_SET_SVC_PARAMS if no frames have
been encoded. AV1E_SET_SVC_PARAMS was missed in the original change.
