Pull request description:
Now that #19991 and #20210 have been merged, we can determine inbound onion peers using `CNode::m_inbound_onion` and add it to the localhost peers protection in `AttemptToEvictConnection`, which was added in #19670 to address issue #19500.
Update 28 February 2021: I've updated this to follow gmaxwell's suggestion in https://github.com/bitcoin/bitcoin/pull/20197#issuecomment-713865992.
This branch now protects up to 1/4 onion peers (connected via our tor control service), if any, sorted by longest uptime. If any (or all) onion slots remain after that operation, they are then allocated to protect localhost peers, or a minimum of 2 localhost peers in the case that no onion slots remain and 2 or more onion peers were protected, sorted as before by longest uptime.
This patch also adds test coverage for the longest uptime, localhost, and onion peer eviction protection logic to build on the welcome initial unit testing of #20477.
Suggest reviewing the commits that move code with `colorMoved = dimmed-zebra` and `colorMovedWs = allow-indentation-change`.
Closes #11537.
