  Make 2024-03-05 changes compile with clang 15
  
  WebKit compiles with this. Constructing with function style cast
  constructor is not supported when the type does not have a constructor.
  Use initializer list construction with explicit name instead. For
  MacroExpander declare a constructor.
  
  Fixed: angleproject:8585
