Summary

This a very basic implementation of the proof download feature via a
getdata message. For now this has zero defense mechanism so it is hidden
behind a flag which disables it by default.

Depends on D9499 for passing the tests.

Test Plan
./test/functional/test_runner.py abc_p2p_avalanche_inventory.py

Question/suggestion: Is it likely we'll want to put other experimental stuff behind this flag in the future? If so, maybe it would it make sense to use a more generic name like "-enableavaexperimental" or similar?

In any case starting it with "-enable" seems good, as it's a flag that turns on a certain behavior.

src/init.cpp
1240 ↗(On Diff #28418)

I intended to remove this flag once the feature is complete, not extending it. The only use is to avoid exposing the node to network requests with no protection.

src/net_processing.cpp
3177 ↗(On Diff #28422)

Good catch, I moved the block without the continue statement. I have no preference on this or a switch, if you do let me know and I'll update
