avutil/frame: add AV_SIDE_DATA_PROP_{SIZE,COLOR}_DEPENDENT
Many filters modify certain aspects of frame data, e.g. through resizing
(vf_*scale* family), color volume mapping (vf_lut*, vf_tonemap*), or
possibly others.
When this happens, we should strip all frame side data that will no
longer be correct/relevant after the operation. For example, changing
the image size should invalidate AV_FRAME_DATA_PANSCAN because the crop
window (given in pixels) no longer corresponds to the actual image size.
For another example, tone-mapping filters (e.g. from HDR to SDR) should
strip all of the dynamic HDR related metadata.
Since there are a lot of different side data types that are affected by such
operations, it makes sense to establish this information in a common, easily
accessible way. The existing side data properties enum is a perfect fit for
this.
