Add PromotedInfixT/PromotedUInfixT to TH
Previously, it was not possible to refer to a data constructor using
InfixT with a dynamically bound name (i.e. a name with NameFlavour
`NameS` or `NameQ`) if a type constructor of the same
name exists.
This commit adds promoted counterparts to InfixT and UInfixT,
analogously to how PromotedT is the promoted counterpart to ConT.
Closes #20773
