[Mono] Intrinsify Quaternion and Plane with LLVM as backend

[fanyang-mono]

Quaternion and Plane need to be intrinsified on all Mono supported platforms.

From Tanner (https://github.com/dotnet/runtime/pull/81335/files#r1091335649)
"Quaternion and Plane should be intrinsified. I don't have enough context into Mono to know if Plane is problematic since it is Vector3, float. I imagine Quaternion just needs to be handled since it has an identical layout to Vector4. However, not all the same functions get lightup for Quaternion and it is non-obvious how to correctly filter things here."
