Reviewed by Adam Barth.

Source/WebCore:

Remove 8 methods that are autogenerated by Settings.in.

No new tests, this is a refactor and is convered by existing tests.

* testing/InternalSettings.cpp:
(WebCore::InternalSettings::Backup::Backup): Remove backup.
(WebCore::InternalSettings::Backup::restoreTo): Remove restore.
* testing/InternalSettings.h:
(Backup): Remove member variables and functions.
(InternalSettings):
* testing/InternalSettings.idl: Remove functions.

LayoutTests:

These tests were manually trying to reset setMediaPlaybackRequiresUserGesture
when the test ended because they weren't using the InternalSettings::Backup to
save/restore the prefs. The autogenerated code will properly reset these prefs
before the next test.
