gdk: Always request "flush events" frame clock phase on events
This change is done for 2 reasons:
- The logic to request this phase when compressing scroll events is
slightly broken. If there are multiple scroll events that are
coalesced into one, the surface frame clock will not get this request.
The worst case is having >= 2 scroll events on every frame, as the
compressed event will be left in the queue, and be further compressed
on future events.
- Even scroll events aside, this phase is requested in oddly specific
places that are not enough to cover all events, others do rely on
unrelated GdkFrameClock activity that happens to flush the events
as well.
Unify this phase request so it explicitly happens on the arrival of any
event. This ensures that events (compressed or not) will be handled
promptly after arrival.

tries to fix things by doing the following:
* Record the GL context type in a more proper fashion, using an Enum. This
makes things a bit cleaner.
* Force GLES-3.0+ contexts, since libANGLE requires this to properly work with
the shaders-its 2.0 contexts don't work well with our shaders.

gskrenderer.c: Use GL renderer on Windows by default
Since now we have the shaders working on Windows under GLES with libANGLE using
a 3.0+ context, drop the check to fall back to the Cairo renderer when GLES is
being used.
