Jake Hillion 03c81cbdb4 tbv2: fix pointer codegen 
A previous change enabled running OIL tests with specific features enabled.
This highlighted that pointer code generation under TreeBuilder-v2 was very
broken. This change updates pointer code generation to work and enables the
skipped tests. All enabled tests need `expected_json_v2` added to them due to
formatting differences.

Reformatted and rewrote the basic type handler that handles primitives and
pointers. Removed the reliance on `features` to decide whether to generate for
TreeBuilder-v2 as the intermediate features have been removed.

There were a couple of other changes needed to enable these tests on TBv2 that
aren't worth their own issues and PRs, I sneaked them in here.

Extra changes:
- Added `Pointer` and `Reference` to TopoSorter so they generate
  `NameProvider` instances. It might be worth visiting the graph differently
  for `NameProvider` as it requires so many instances that others generators do
  not. Will consider that in the future.
- Follow typedefs when calculating exclusive size for a type.

Closes #458.

Test plan:
- CI
- Enabled previously disabled tests.

Object Introspection is a memory profiling technology for C++ objects. It provides the ability to dynamically instrument applications to capture the precise memory occupancy of entire object hierarchies including all containers and dynamic allocations. All this with no code modification or recompilation!

For more information on the technology and how to get started applying it to your applications please check out the Object Introspection website.
