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

[jeffro256]

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

I can build v0.18.3.4 on macOS by applying this PR, but I'm still getting this error building monero-cpp, when importing cryptonote_basic/account.h:

Any ideas?

Any ideas?

Found the fix, to add rct::sk2rct to keys within monero-cpp.

[jeffro256]

@woodser, as @vtnerd pointed out, it would be a good idea to use unwrap(unwrap(s)) instead of rct::sk2rct(s) because it is more explicit, and rct::sk2rt might copy in the future.

Any chance we could merge this PR to the release branch, to fix the build for folks on macOS?

Otherwise our build is broken, which is making development of PRs across people difficult.
