This is a reland of 5fcfcea4
Re-land uses static linking with angle_util. The root cause
of the CFI error wasn't solved. Static linking works around
the problem by not using any export rules.
Second re-land fixes missing imports for libEGL and libGLESv2
static varieties.
Original change's description:
> Add more test_utils functions.
>
> Includes methods for creating temporary files, deleting files, and
> reading files into a string. Also renames GetPathSeparator to mention
> it's only used for environment variables. Includes a new virtual type
> angle::Process that will be used to implement cross-platform async
> Process launching for tests. Also includes a way to specify a custom
> crash handler callback.
>
> Also adds a few unit tests for the new functionality. They are disabled
> on Android because the functions are not needed by the new test runner.
