Allintra: Introduce sf enable_intra_mode_pruning_using_neighbors

This CL introduces a speed feature
enable_intra_mode_pruning_using_neighbors to prune specific intra
modes in nonrd path based on source variance and best mode so far
only if current mode is not the winner mode of both the
neighboring blocks. This speed feature is enabled for allintra,
speed 9.

For AVIF still-image encode,
