Set disable-gpu-process-crash-limit flag for CEF

[notr1ch]

Description

One of our top OBS crashers is CEF crashing the entire process if its GPU process crashes too much. Until we can figure out why the GPU is crashing so much for some users, avoid crashing OBS entirely and just have broken browser sources instead.

Motivation and Context

Avoid CEF bringing down OBS on GPU errors.

How Has This Been Tested?

Hasn't - I am unable to reproduce the GPU issues.

Note that this setting disables GPU fallback modes too, so if HW acceleration repeatedly crashes, CEF won't fall back to software. There's no setting to disable the crashing while still enabling fallback unfortunately.
