Improve key frame detection

This patch adds a function to the key frame detection to test
for specific patterns in the intra signal in the first pass stats
that tend to be indicative of a key frame.
This is intended to compliment the existing code and finds some
scene cuts that were previously being misssed.
Tested on two clips where the existing code was struggling to
identify the key frames this patch improved detection as follows.
Film clip 1: (detected / actual)
Old (2/5) New (5/5)
Film Clip 2
Old 4/11 and one false +, New 7/11 and 1 false +.
Short 4K Film Scene
Old 1/2 New 2/2
In testing so far I have not seen many extra false +'s though
it is likely that there will be some cases and this may need
further tweaking.
One one of our longer form film test reels ~20k frames)
the change picked up around 35 key frames that were
previously missed, mainly in darker scenes. There were a few
extra (or different) false positives cause by bright flashes or
explosions but these were cases where there was little
difference between inter and intra coding.
Awaiting testing on standard sets.

Change to mode early breakout rules for FILM mode.
The biggest offender in terms of preventing retention of film
grain in high rate film content is the use of DC-PRED mode.
Some of the directional modes whilst not strictly preserving
grain do better at at least preserving some texture.
This change blocks the early breakout of the rd loop based
on the reference frame giving the best result so far. In practice,
unless DC-PRED was chosen as the best mode so far, the other
directional intra modes would not even be considered.
As the film grain mode also tends to bias against DC-PRED (or
intra in general) this was pretty much blocking all use of directional
intra modes.
The patch also allows for a broader spectrum of DC modes at the
16x16 transform level than previously.

Store a group level noise metric from first pass.
Adds a variable to GF group structure to store a noise
energy metric for the current group that can be used
in things like film grain retention code.

vp9-screen: Fix to screen wth layered encoding
zero_temp_sad_source is only computed when
compute_source_sad_onepass and sf->use_source_sad are
on, which currently is only for the top layer of the
layered encoding. So qualify the usage of
zero_temp_sad_source on those flags.
This affects the quality/speed of the lower layers of
screen content mode when SVC (quality layers) are used.
