Mac: Disable CATransactionGPUCoordinator to test crash theory

Crashes with content::GpuProcessHost::OnProcessCrashed on the stack
have become prevalent in Chrome 69.

CATransactionGPUCoordinator was introduced in the first Canary to
exhibit these crashes (https://crrev.com/565687 in 69.0.3455.0).

Disable CATransactionGPUCoordinator to test the theory that it is
responsible for the crashes. This will make window resize slightly
jankier (like -- the window's contents will detach from the window
during resize) while disabled. Note that not all window resize logic
is disabled by this -- just the GPU side (so resize will be reasonable
most of the time, but there will be occaisonal glitches now).
