This is a follow-up from PR #122545, which enabled converting yaml to contextual profiles. This change uses the lower level yaml APIs because: - the mapping APIs `llvm::yaml` offers don't work with `const` values, because they (the APIs) want to enable both serialization and deserialization - building a helper data structure would be an alternative, but it'd be either memory-consuming or overly-complex design, given the recursive nature of the contextual profiles.
