Revert "Enable graphite field trial on Android"

This reverts commit 0d6f3f0d4a560deded1fa7f4194ea6d3fb408fa1.

Reason for revert: Significant regressions.

Original change's description:
> Enable graphite field trial on Android
>
> This enables SkiaGraphite in fieldtrial_testing_config.json for Android.
> This only causes *some* Android devices to run graphite, namely devices
> that were already running Ganesh/Vulkan. This will cause a change on
> some bots, such as Pixel 6, Pixel 7 and Samsung S23. Most Android bots
> with older hardware will not see any change.
>
> This is expected to cause a regression on Pixel 6 perf bots. The
> benchmark stories start with a clear slate and empty shader cache.
> Graphite shaders are bigger than Ganesh shaders and take longer to
> compile. With graphite there is a significant delay compiling shaders at
> the start of each story which negatively impacts metrics. There are real
> performance regressions mixed in with this shader compilation delay as
> well that will need to be fixed before launch.
