Converted to gtest, writing output files properly and no longer uses exceptions.

This test now runs and fails as a gtest should (previously it always
exited with 0 even if the tests failed).
The audio_coding_module_test target no longer uses exceptions in the generated project.
Output files are written to our global output folder, using
testsupport/fileutils.h.

BUG=
TEST=audio_coding_module_test on all platforms, in Debug+Release
