fix[mpp_sys_cfg]: Fix abnormal stride calculation.

Browse source 
Platform: General

Error case:
If the specification specifies a stride, it should be
configured according to the specification's stride rather
than calculated based on width and height, especially
in scenarios involving H.264 field-based sources.
For the case of FBC, hor_stride needs to be processed
based on pixels and is unrelated to bit depth.
