Capture script usage is the same as before, but all frames are combined
into a single file which shares the images between frames, reducing the
file size and serialization time somewhat. This brings us closer to the
objective of realistic performance measurements, but to do that
correctly, a second format is needed, (skbug.com/9174)
Single frame captures still produce the same format.
Test: The method used for serialization is tested in skia's DM unit
tests, in MultiSkpTest.cpp
Test: Tested manually with the libs/hwui/tests/scripts/skp-capture.sh script

Convert SkiaPipeline::skpCaptureEnabled into a system property.
Add ability to capture drawing in layers. Add ability to capture
animations/sequence of frames. Fix crash when recording a
TextureView.
Test: Ran capture script.

Create a script that can parse systrace files and calculates
metrics. The example metrics are average DrawFrame and average
time to record a View.
Test: ran the script and compared outputs with numbers visible,
when systrace file is opened in a browser.
