Extract crypto helpers into shared ObliviousXHelpers library
Motivation:
This change extracts shared cryptographic helper functions from ObliviousX into a separate ObliviousXHelpers library to prepare for implementing Oblivious DNS over HTTPS (ODoH) support, which will require the same cryptographic primitives.
Modifications:
ObliviousXHelpers
target with HPKE extensions and utility functionsResult:
After this change, cryptographic helpers are available as a shared library for both existing ObliviousX and upcoming ODoH implementations, eliminating code duplication.
