This CL adds a new way to set the start frame of a capture.
It adds a new environment variable called ANGLE_CAPTURE_TRIGGER
that, when set, will be used instead of frame start and end.
By setting ANGLE_CAPTURE_TRIGGER to a non-zero value, ANGLE will
capture that many frames when the value changes. For example,
on Android, we can set it with:
adb shell setprop debug.angle.capture.trigger 20
When we reach the target content, set the value back to zero:
adb shell setprop debug.angle.capture.trigger 0
and ANGLE will start capturing 20 frames.
Currently only hooked up for Android, but should be possible to
support on other platforms.
Test: Capture application frames using trigger

Multiple tests are run in paralell to squeeze the most out of CPUs.
Tests are stored in a work queue. Whenever a CPU becomes available,
the next unrun test is grabbed and run on a spawn process on that CPU.
Each cpu gets their own environment and build folders and trace folders
so that tests don't overwrite each other.

Gives about a 2-3x reduced data file size. Should help reduce the time
we spent transferring trace files on Android.
This feature is implemented as a parameter to the capture/replay tool.
This keeps backwards compatiblity if we ever need to integrate a cpp
replay into an environment that doesn't have access to zlib for
decompression.
We'll need to update the traces to take advantage of the compression.

Add an optional parameter (ANGLE_CAPTURE_LABEL) to
ANGLE frame capture that tags files and functions
uniquely, allowing multiple frame captures to be
replayed by a test harness.
Example:
ANGLE_CAPTURE_LABEL=foo
Results in filenames like this:
foo_capture_context1.cpp
foo_capture_context1.h
foo_capture_context1_files.txt
foo_capture_context1_frame000.angledata
foo_capture_context1_frame000.cpp
foo_capture_context1_frame001.angledata
foo_capture_context1_frame001.cpp
...
Functions wrapped in namespaces like this:
namespace foo
{
void ReplayContext1Frame0();
void ReplayContext1Frame1();
}
For use like this:
foo::SetupContext1Replay();
for (...)
{
foo::ReplayContext1Frame(i);
}

This index file lets us very easily write a generic capture sample.
Previously the dev had to maintain a list of multiple sources files.
Potentially hundreds. By writing the source file list to an index file
we can load this easily in GN as a variable and plug that into the
sources.
Also updates docs.

Mid-execution replay starts the replay from a specific start frame
instead of frame 0. Integration tests will then run between the start
and end frames. This lets us make much smaller reproduction cases from
large benchmarks or applications.
We implement mid-execution replay via a cpp "Setup" function. The
replay test will run the setup function before the starting frame. Test
execution proceeds normally after setup.
Currently we do not implement mid-execution capture. We run capture on
all frames. Including frames before the start frame. We do this to
intercept compiled shaders and programs for easier caching. This could
be changed in the future to also start capture mid-execution. Mid-
execution capture might require using ProgramBinary calls to capture
shader and program data.
Many captures are unimplemented. Several comments indicate missing
functionality. There's a lot we can add as we explore replaying more
complex applications and higher GL versions. We will also need some
kind of state reset functionality so we can run the replay in a loop.

This file will be used with multi-frame captures to share common code.
Common code is global state, resource maps, and a list of frame replay
functions. This should make converting a CPP replay into a functional
test quite a bit simpler. The replay files will now be something like:
angle_capture_context1.cpp
angle_capture_context1.h
angle_capture_context1_frame000.cpp
angle_capture_context1_frame001.cpp
... etc
Also adds a template for adding a capture/replay sample. Instructions
are located in samples/BUILD.gn and docs in doc/CaptureAndReplay.md.

Introduces a few ways of controlling capture via:
* `ANGLE_CAPTURE_ENABLED`:
Can be set to "0" to disable capture entirely.
* `ANGLE_CAPTURE_OUT_DIR`:
Can specify an alternate directory than the CWD.
* `ANGLE_CAPTURE_FRAME_END`:
This variable can override the default of 10 frame to capture.
Also adds a simple usage guide document.
