gl-renderer: Add support for fence sync extensions
Check for the EGL_KHR_fence_sync and EGL_ANDROID_native_fence_sync
extensions and get pointers to required extension functions.
These extensions allow us to acquire GPU timestamp information
asynchronously, and are required by the upcoming work to add
rendering begin/end timepoints to the weston timeline.
