Reviewed by Ojan Vafai.

Source/WebCore:

Remove 6 methods that are now autogenerated.
setAcceleratedFiltersEnabled was never called.
AcceleratedCompositingForOverflowScrollEnabled was never backed up/restored.
setEnableCompositingForFixedPosition and setEnableCompositingForScrollableFrames
are renamed to match the name in Settings.in.

No new tests, there should be no change in behavior. This is covered by
existing tests in compositing and platform/chromium/compositing.

* testing/InternalSettings.cpp:
(WebCore::InternalSettings::Backup::Backup): Remove code.
(WebCore::InternalSettings::Backup::restoreTo): Remove code.
* testing/InternalSettings.h:

(InternalSettings):
* testing/InternalSettings.idl: Remove methods that are no longer used.

LayoutTests:
