This diff removes the -bypassnetgrouplimit flag in favor of a permanent bypass for the avalanche outbounds. It also fixes a couple issues that are preventing connecting non avalanche outbounds after we connected enough avalanche peers:

• The outbound type counters have fallthrough path that cause the non avalanche outbound count to be wrong.
• The group limit should still apply to non avalanche peers in the fallback case, when we couldn't find an avalanche peer.

Depends on D11833.
