Tidy up and refactor wildcard handling
When examining #10615, I found the wildcard handling hard
to understand. This patch refactors quite a bit, but with
no real change in behaviour.
* Split out TcIdSigInfo from TcSigInfo, as a separate type,
like TcPatSynInfo.
* Make TcIdSigInfo express more invariants by pushing the
wildard info into TcIdSigBndr
* Remove all special treatment of unification variables that arise
from wildcards; so the TauTv of TcType.MetaInfo loses its Bool
argument.
A ton of konck on changes. The result is significantly simpler, I think.
