Backport of #111000 to release/9.0-staging. Fixes storing of Vector3 into memory on mono-llvm-aot.
Customer Impact
Reported in #110820. Storing Vector3 into memory was is working incorrectly when using mono aot llvm. Instead of being saved as Vector3 it is saved as Vector4 (Vector3 + trailing 0) effectively overwriting the next memory cell with 0. Customer experienced their data being overwritten with 0s.
Regression
Regression introduced in #97416. This change implemented some intrinsics for Vector3 - for those intrinsics purposes Vector3 is being represented as Vector4 (Vector3 + 0).
Testing
Added test a new test verifying that saving Vector3 works correctly.
Risk
Low. Change applies only to mono aot llvm Vector3 save to memory path.
