    Add UInfixT to TH types (fixes #10522)
    
    UInfixT is like UInfixE or UInfixP but for types. Template Haskell
    splices can use it to punt fixity handling to GHC when constructing
    types.
    
    UInfixT is converted in compiler/hsSyn/Convert to a right-biased tree of
    HsOpTy, which is already rearranged in compiler/rename/RnTypes to match
    operator fixities.
    
    This patch consists of (1) adding UInfixT to the AST, (2) implementing
    the conversion and updating relevant comments, (3) updating
    pretty-printing and library support, and (4) adding tests.
    
    Test Plan: validate
