LLVMMDStringInContext and LLVMMDNodeInContext are deprecated, replace them with LLVMMDStringInContext2 and LLVMMDNodeInContext2.
Also replace Value with Metadata in some function signatures for better consistency.

☔ The latest upstream changes (presumably #130519) made this pull request unmergeable. Please resolve the merge conflicts.

I unintentionally duplicated this effort in #130503. My PR looked extremley similar to this one, although I didn't add Metadata to BackendTypes. Anyway, looks good to me.

Can we add a set_metadata method that does the LLVMMetadataAsValue + LLVMSetMetadata dance?

LLVM should really allow setting the metadata without first wrapping it in a value and then unwrapping again, but we can at least hide this...

Accept MetadataType here and move the c_uint cast into the method?

Ah crap, I didn't realize that bors retry also retires try builds. I'll just let it run to avoid confusing bors further.

Huh, and now it failed again. So probably something is legitimately wrong with this patch that makes things break non-deterministically -- but I'm not able to spot it.
