Give better errors for code corrupted by Unicode smart quotes (#21843)

Previously, we emitted a generic and potentially confusing error during lexical
analysis on programs containing smart quotes (“/”/‘/’). This commit adds
smart quote-aware lexer errors.

Buglet in GHC.Tc.Module.checkBootTyCon

This lurking bug used the wrong function to compare two
types in GHC.Tc.Module.checkBootTyCon

It's hard to trigger the bug, which only came up during
!9343, so there's no regression test in this MR.
