cleanup EGL extensions strings and entry-points
- move all the code related to EGL extensions in one place
- add missing extension strings:
EGL_KHR_lock_surface
EGL_KHR_reusable_sync
- add public extensions strings and entry-points
EGL_ANDROID_wait_sync
EGL_ANDROID_presentation_time
- add missing entry-points for EGL_KHR_reusable_sync
