egl: Add helpers to manage and wait for EGLSync objects

Browse source 
This adds meta_egl_create_sync and meta_egl_destroy_sync to be able to
create and dispose EGLSync objects, respectively, as well as
meta_egl_wait_sync to be able to wait for an EGLSync on the GPU.

(cherry picked from commit d2e70c15ec1cf6b6f7cd8c8825a5d92a1f89b35b)
