Revert "oop raster: Plumb linux font service to the gpu process."

This reverts commit c44ffb1d59079c072e6f188c0775ed665e854c42.

This is no longer needed as fonts have been implemented as a
separate path.

commit c87477e182ca509e3ab7f15e91aa67e2af633bd2

Add about:flags plumbing for OOP-R

Currently, out of process rasterization (oop-r) is controlled by a
single command line flag (--enable-oop-rasterization) and default off.
Many places in the code check this.

This patch centralizes the enabling logic into gpu_util.cc and
GpuFeatureList as the definitive source for whether oop-r is enabled.

First, command line entries are forwarded via GpuPreferences to the gpu
process.  Then, GpuInfo decides whether or not oop-r can be supported.
Then the gpu preferenes (enable and disable), blacklist, and finch entry
(default off now) are used to set the GpuFeatureInfo status value.  This
status value is passed to gles2::FeatureInfo to enable/disable
chromium_raster_transport in the raster decoder if needed for oop
raster.

The command line flags no longer need to be piped to the renderer or the
gpu process.  The renderer also uses the GpuFeatureInfo to figure out
whether to use oop-r.  If it says it is supported, then it should be
used.

gpu: Always detect oop raster support

If this is only based on preferences (which is based on command line),
then it is impossible to turn on oop raster via a finch trial.

This fixes up a bug introduced while trying to fix bots in c87477e.
