Reviewed by Eric Seidel.

VoidCallback is the oldest of the callbacks and it predates our ability
to autogenerate callback objects. The existing implementation of
VoidCallback is wrong because it doesn't call
ActiveDOMCallback::canInvokeCallback. The net result of that is that
void callbacks can race with navigations and occationally execute after
the Frame has navigated to a new Document, which was causing the
flakiness.

This patch changes VoidCallback to no longer be a unique snowflake.
Instead, we autogenerate the implementation, just like every other
callback in WebCore.

Tests: storage/websql/database-lock-after-reload.html is no longer flaky.
