egl/dri2: Consolidate eglTerminate

egl_dri2.c:dri2_terminate() handled terminating X11 and DRM displays.
The Wayland platform implemented its own dri2_wl_terminate(), which was
nearly a copy of the common one.

To implement the EGL platform extensions, we either need to dispatch
eglTerminate per display or define a common implementation for all
platforms. This patch chooses consolidation.  It removes
dri2_wl_terminate() by folding it into the common dri2_terminate().

It was necessary to invert the `if (disp->PlatformDisplay == NULL)` and
the switch statement because, unlike DRM and X11, Wayland's terminator
performed action even when EGL didn't own the native display. In the
inversion, I replaced `disp->PlatformDisplay == NULL` with
`dri2_dpy->own_device` because the two expressions are synonymous, but
the latter's meaning is clearer.
