Optimize quantize_fp_neon function for LBD and HBD

Optimized EOB calculation by removing iscan adjustment in
get_max_lane_eob(). Move this logic to get_max_eob(), which adds 1 to
the maximum value.

Use -1 instead of 0 when comparing against iscan values, to
differentiate between the case when non-zero element is at position 0
and that one where no non-zero value exists.

This is a port from SVT-AV1:
