Looks good, but please address @matklad comments about tests

The ProtocolFeature is a natural entry point for learning about implications of a particular feature, so I think comments on enum variants here have high leverage -- you can say little, but that wouldn't require ongoing maintanence, will help other people, and could be copy-pasted into the feature stabilization PR.

As an alternative, I'd write this as
let (_outcome, err) = ...
assert_eq!(err, None);
Explicit tuple unpacking with naming of the ignored components improves readability.
While working with #4954, initially I put new test into `contract_preload` test file, though `invalid_contracts` turned out to be a better place. Rename test files, hope this will make the choice of places for new tests in the future clearer. Test plan --------- Existing tests.
Stabilize limiting functions number in a contract to 10_000: #4954 While discussing #4826, we found that both contract compilation and function call require a lot of time, if number of wasm functions in it is huge. Even if we fix contract size, function number still makes a big difference. To mitigate this issue, we limit number of functions in a contract. This shouldn't affect current mainnet contracts because maximal number of functions is ~5k. ## Test plan * http://nayduck.near.org/#/run/2223 * existing tests
Limit max contract functions number to
200010000.See corresponding Zulip thread for more details.
