Parse additional line introduced in the microdump format and containing the GPU infromation in the following format:

G GL_VERSION|GL_VENDOR|GL_RENDERER.

The GPU version, vendor and renderer are extracted during microdump parsing and populated in the appropriate fields in the SystemInfo struct.

This is to match the changes introduced in crrev.com/1343713002 and crrev.com/1334473003
