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.

Please take a look at tools/v8windbg/README.md for an overview of what
v8windbg can do and how it's structured. This platform-specific
debugging plugin makes use of the data provided by the V8 postmortem
debugging API in tools/debug_helper.
Note: This code began as https://github.com/billti/v8dbg and then moved
into the Edge repository, where I added features gradually and got code
reviews for individual changes. Now, taken in its entirety, it's an
obnoxiously large CL. I'm open to breaking it up into a few chunks if
that would be preferable.
