Upgrade Embree to the latest official release.

Browse Source 
Since Embree v3.13.0 supports AARCH64, switch back to the
official repo instead of using Embree-aarch64.

`thirdparty/embree/patches/godot-changes.patch` should now contain
an accurate diff of the changes done to the library.

(cherry picked from commit 767e374dce)
