Disable minimode scavenger in GPUProcess
https://bugs.webkit.org/show_bug.cgi?id=245681
rdar://100286875
Reviewed by Geoffrey Garen.
GPUProcess CPU usage during YouTube playback regressed by ~10% in the last
major release. About 30%
of that is coming from extra activity in the scavenger thread due to increased
scavenger frequency
(242195) and work (235347).
To work around this, disable the mini mode scavenger entirely in GPUProcess.
This is neutral for
both Membuster and RAMification.
