Fix tcTyClTyVars to handle SigTvs
Previously, tcTyClTyVars required that the names of the LHsQTyVars
matched up exactly with the names of the kind of the given TyCon.
It now does a bit of matching up when necessary to relax this
restriction.
This commit enables a few tests that had previously been disabled.
The shortcoming this addresses is discussed in #11203, but that
ticket is not directly addressed here.
Test case: polykinds/SigTvKinds, perf/compiler/T9872d
