Package-private abstract methods on KEM prevent users from implementing custom KEMs (e.g. XWing) outside the org.bouncycastle.crypto.hpke package, requiring them to place subclasses inside the BC package as a workaround. Promote all abstract methods on KEM from package-private to protected. Update DHKEM.getEncryptionSize() to match — it was the only remaining package-private override; all other DHKEM overrides were already public or protected. This is a source-compatible change: existing subclasses (DHKEM) that override with broader visibility (public/protected) are unaffected.
