Fix assertion when DOM Rendering in GPU Process is enabled with accelerated drawing disabled
https://bugs.webkit.org/show_bug.cgi?id=237626
Reviewed by Tim Horton.
Override releaseGraphicsContext() in the base class (which asserts). This subclass
doesn't need to do anything; releaseGraphicsContext() is only relevant for IOSurface-
based backends.
