drm/i915/fb: Rename i915_color_plane_view::stride to mapping_stride

The next patch needs to distinguish between a view's mapping and scanout
stride. Rename the current stride parameter to mapping_stride with the
script below. mapping_stride will keep the same meaning as stride had
on all platforms so far, while the meaning of it will change on ADLP.

No functional changes.
