Adjust 64-bit ARM data layouts for LLVM update
LLVM has updated data layouts to specify `Fn32` on 64-bit ARM to avoid C++ accidentally underaligning functions when trying to comply with member function ABIs. This should only affect Rust in cases where we had a similar bug (I don't believe we have one), but our data layout must match to generate code. As a compatibility adaptatation, if LLVM is not version 19 yet, `Fn32` gets voided from the data layout. See llvm/llvm-project#90415
