avcodec/libsvtav1: give svtav1-params priority over avctx values

If the svt equivalent option to an avctx AVOption is passed by the user
then it should have priority. The exception are fields like dimensions, bitdepth
and pixel format, which must match what lavc will feed the encoder after init.

This addresses libsvt-av1 issue #1858.
