Rollup merge of #67033 - cuviper:ValueName2, r=rkruppe

Migrate to LLVM{Get,Set}ValueName2

The deprecated `LLVM{Get,Set}ValueName` only work with NUL-terminated
strings, but the `2` variants use explicit lengths, which fits better
with Rust strings and slices. We now use these in new helper functions
`llvm::{get,set}_value_name` that convert to/from `&[u8]`.

Closes #64223.
