2bef14c1 - [CIR][NFC] Move builtin tests to their own directory (#169737)

[CIR][NFC] Move builtin tests to their own directory (#169737) This moves all builtin-related CodeGen tests to a new directory, separate from the main clang/test/CIR/CodeGen directory. This will make it easier to run the basic CodeGen tests without running the builtin tests. This is specifically intended to move those tests which include `immintrin.h` or any of its variants, which take a very long time to compile with a debug build.
