Vadim Petrochenkov 79f0d88de8 resolve: Use feature(custom_attribute) fallback only if the feature is enabled
Normally `#![feature(...)]` shouldn't change behavior, but custom attributes in particular are in the process of retirement, and we should not produce a message telling to enable them.
It also helps with unifying diagnostics for unresolved macros.
