[FIX][LLVM] Workaround -mcpu=apple-latest for llvm above 18.0 (#17492)

[cbalint13]

This PR address a fix for #17492

• It seems that LLVM version >= 19 misses the mcpu apple-latest in the llvm backend.
• Relevant LLVM change makes this alias unavailable, but works from llc/clang higher frontends.

Error:

llvm_instance.cc:226: Error: Using LLVM 19.1.2 with `-mcpu=apple-latest` is not valid in `-mtriple=arm64-apple-macos`, using default `-mcpu=generic`
llvm_instance.cc:226: Error: Using LLVM 19.1.2 with `-mcpu=apple-latest` is not valid in `-mtriple=arm64-apple-macos`, using default `-mcpu=generic`

Notes

print( "LLVM version = [%s]" % tvm.target.codegen.llvm_version_major() )
print( tvm.target.codegen.llvm_get_cpu_archlist(tvm.target.Target("llvm -mtriple=arm64-apple-macos")) )
