evas-wayland-egl: Fix missing support for EVAS_NATIVE_SURFACE_WL

Summary: Support for using EVAS_NATIVE_SURFACE_WL was missing/incomplete in the
wayland_egl engine. This commit addresses that issue so that now the
wayland_egl engine can support both EVAS_NATIVE_SURFACE_OPENGL and
EVAS_NATIVE_SURFACE_WL.

@fix
