Make it possible to run WebGL conformance tests on Android

Make it possible to run WebGL conformance tests on Android

This patch implements the following changes to make it possible to run
the WebGL conformance test suite on Android:

    1. Copy WebGL test data files to the device.

    2. When running the conformance test, turn on WebGL with the
    --enable-webgl command line flag.

    3. Avoid validating the PCI vendor and device ids for the GPU because
    Android has no such concept.

With these changes, you can run the WebGL conformance test by first
building content_browsertests_apk, removing the WebGL exclusion from 
build/android/pylib/gtest/filter/content_browsertests_disabled and then executing:

    $ build/android/run_browser_tests.py -f WebGLConformanceTest.*

This gets WebGL tests going on Android. PTAL.

These changes LGTM, but please ask zmo for a review too.

Note that the GPU team is moving away from running the WebGL conformance tests
in content_browsertests, instead running them via Telemetry, because of
reliability problems seen on Windows with content_browsertests. However, getting
these tests running now in this form is a good idea.

LGTM

Thanks for the hint about the move to telemetry. This looks like the bug for
tracking that: http://crbug.com/225939.

bulach@, mind checking the change under build/android/pylib? Thanks.

lgtm for android/pylib, thanks!
