egl: add eglSwapBuffersWithDamageKHR

EGL_KHR_swap_buffers_with_damage is actually already supported, as it is
technically nothing but a rename of EGL_EXT_swap_buffers_with_damage.

To that effect, both extension are advertised depending on the same
condition, and the new entrypoint simply redirects to the previous one.
