fix[mpp_sys_cfg]: Fix stride issue on resolution change

Browse source 
Platform: General
Spec: vp8/vp9/mpeg2

Error case:
Stride information persists incorrectly across
resolution changes, leading to errors.

Solution:
When the stride is not set externally, it needs to
be set to 0 to avoid the stride not being updated
in time when the resolution of the same source
changes. For example, the source:
VP9_crowd_run_2048X1088_60fps_bd8_frm_resize_l41.webm
contains two resolutions: 2048x1088 and 1365x725

Source:
VP9_crowd_run_2048X1088_60fps_bd8_frm_resize_l41.webm
