build: fix build with Boost 1.85 and remove instances of viewkey logging [RELEASE]

1. Use std::is_standard_layout and std::is_trivially_copyable instead of std::is_pod for KV byte-wise serialization, which fixes compile issue for Boost UUIDs
2. Removed reimplementation of std::hash for boost::uuids::uuid
3. Removed << operator overload for crypto::secret_key
4. Removed instances in code where private view key was dumped to the log in plaintext

Release version of #9450, containing C++14 modified assertions
