CG display list graphics contexts are sometimes still flipped

Reviewed by Dean Jackson.
* Source/WebKit/Shared/RemoteLayerTree/CGDisplayListImageBufferBackend.mm:
(WebKit::GraphicsContextCGDisplayList::GraphicsContextCGDisplayList):
Remove the workaround introduced in r252402@main, since we have reinstated
the toplevel
context flip in 258997@main. I missed this in 258997@main because it only
affects
cases where we end up doing setCTM(getCTM()), which is just rare enough to
miss
with cursory testing.
* Source/WebKit/Shared/RemoteLayerTree/RemoteLayerBackingStore.h:
* Source/WebKit/Shared/RemoteLayerTree/RemoteLayerBackingStore.mm:
(WebKit::RemoteLayerBackingStore::paintContents):
(WebKit::RemoteLayerBackingStore::drawInContext):
While debugging the above, I also noticed that we were leaving the display
list context with a missing trailing `restore` operation, because we encode
the
display list inside drawInContext. To avoid this, move the flip inside our
existing
state saver, which is popped before encoding the display list. This has no
actual effect at the moment (except making the dumped list look more
correct),
but will eventually be necessary when the replayed destination context is
reused.
