I cannot figure out a good way to generate an `ld` command
that works on both Linux and macOS. Normally you'd use something
like `AC_LINK_IFELSE` for this purpose (I think), but that won't
let us test response file support.

I've turned almost all occurrences of TcRnUnknownMessage in GHC.Rename.Module
module into a proper TcRnMessage.
Instead, these TcRnMessage messages were introduced:
TcRnIllegalInstanceHeadDecl
TcRnUnexpectedStandaloneDerivingDecl
TcRnUnusedVariableInRuleDecl
TcRnUnexpectedStandaloneKindSig
TcRnIllegalRuleLhs
TcRnBadAssocRhs
TcRnDuplicateRoleAnnot
TcRnDuplicateKindSig
TcRnIllegalDerivStrategy
TcRnIllegalMultipleDerivClauses
TcRnNoDerivStratSpecified
TcRnStupidThetaInGadt
TcRnBadImplicitSplice
TcRnShadowedTyVarNameInFamResult
TcRnIncorrectTyVarOnLhsOfInjCond
TcRnUnknownTyVarsOnRhsOfInjCond
Was introduced one helper type:
RuleLhsErrReason

instead of a boolean flag for `CDictCan.cc_pend_sc`.
Pending givens get a fuel of 3 while Wanted and quantified constraints get a fuel of 1.
This helps pending given constraints to keep up with pending wanted constraints in case of
`UndecidableSuperClasses` and superclass expansions while simplifying the infered type.
Adds 3 dynamic flags for controlling the fuels for each type of constraints
`-fgivens-expansion-fuel` for givens `-fwanteds-expansion-fuel` for wanteds and `-fqcs-expansion-fuel` for quantified constraints
Fixes #21909
Added Tests T21909, T21909b
Added Note [Expanding Recursive Superclasses and ExpansionFuel]
