Relanding 61718.

I disabled the GPU watchdog in three new cases:
- If the OSMesa software renderer is in use. This will disable it on bots.
- When running on valgrind, whether on a bot or locally.
- In debug builds

I added a GPU process initialization time to the GPU info.

I moved the GPU initialization code outside the watchdog protection because it can take a long time and trigger the watchdog.

I increased the timeout. I set up a field trial with different timeouts to see the rate of failure for each period.

I made ui_tests always run with OSMesa, for consistent operation on bots and when run locally.

Original CL description:

I added a watchdog thread that intermitently checks the main thread can respond
to tasks posted on its message queue.

I fixed some bugs that preventede GGL from failing when the GPU channel was
lost.

Added a command line swith to disable the watchdog thread for debugging
purposes.

TEST=try, local testing of all features
BUG=none
