Seth Brenith 8b1a5681de [tools] Fix v8windbg behavior on Map's bit_field2
Bill kindly pointed out to me that v8windbg was not handling bit_field2
correctly. The issue was that the constexpr type for ElementsKind was,
somewhat unsurprisingly, "ElementsKind", but v8windbg expected a fully-
qualified type name like "v8::internal::ElementsKind". This change
addresses the problem in two ways:
1. Update v8windbg's type resolution logic to resolve type names as if
   they were used in the v8::internal namespace. This makes it more
   consistent with how those type names are used in other generated
   Torque code, reducing surprises and the number of times we have to
   write `v8::internal::` in .tq files.
2. Add compile-time verification that any constexpr type name used as a
   string in class-debug-readers-tq.cc can also resolve as a type name.
