[llvm] [LLVM-C] Move LLVMDISubrangeTypeMetadataKind to end of LLVMMetadataKind enum (PR #132268)

[via llvm-commits]

https://github.com/alan-j-hu created https://github.com/llvm/llvm-project/pull/132268

Inserting a new enum constant in the middle of the enum breaks the ABI for that enum. Commit e298fc2 introduced this issue, which was revealed because the OCaml binding tests failed.
