LOG: [lldb][test] TestCCallingConventions.py: skip on older AArch64 compilers

With our Clang-15 arm64 CI this test-case crashes when compiling the test program:
```
user/jenkins/workspace/llvm.org/lldb-cmake-matrix/llvm-project/lldb/test/API/lang/c/calling-conventions/ms_abi.c
Unexpected callee-save save/restore opcode!
UNREACHABLE executed at /Users/ec2-user/jenkins/workspace/llvm.org/lldb-cmake-matrix/clang_1501/llvm/lib/Target/AArch64/AArch64FrameLowering.cpp:1129!
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
