Emit weird lint name lints after expansion

Browse Source 
Previously, we were emitting weird name lints (for renamed or unknown lints)
before expansion, most importantly before cfg expansion.
This meant that the weird name lints would not fire
for lint attributes hidden inside cfg_attr. The same applied
for lint level specifications of those lints.

By moving the lints for the lint names to the post-expansion
phase, these issues are resolved.
