rtc-screen: Fix to part_early_exit_zeromv with aq=3

The part_early_exit_zeromv feature in the variance
partition was conditioned on cyclic refresh being applied.
This causes high rate fluctuation at very low Q, when
the cyclic_refresh is suddenly turned off, and prevents
the encoded bitrate to go down (for static content at min q).

Removing the cyclic refresh condition allows the encoded
bitrate to go close to zero at min q encoding, when the
cyclic refresh is turned off.

Also add a conditions of x=30 frames from key frame
in order for skip feature to be testd.

This generally has bdrate gain over rtc_screen set,
and completely changes the curve for screenshare_stationary.
Also it will undershoot for a few clips at higher bitrates
(screen_recording and slides_webplot) since they can settle
down to the min-q.
