e6ef90db6c avfilter/bwdif: account for chroma sub-sampling in min size calculation 
The current logic for detecting frames that are too small for the
algorithm does not account for chroma sub-sampling, and so a sample
where the luma plane is large enough, but the chroma planes are not
will not be rejected. In that event, a heap overflow will occur.

This change adjusts the logic to consider the chroma planes and makes
the change to all three bwdif implementations.

Fixes #10688
