Jake Hillion 40af807d8b tbv2: support capture-thrift-isset 
Support the capture-thrift-isset feature with TreeBuilder-v2. Fairly minor
changes here except the type of the Enum in a template parameter now matters.

We follow the previous behaviour of capturing a value for each field in a
struct that has an `isset_bitset`. This value is a VarInt captured before the
C++ contents of the member. It has 3 values: 0 (not set), 1 (set), and 2
(unavailable). These are handled by the processor and represented in the output
as `false`, `true`, and `std::nullopt_t` respectively.

Changes:
- Add a simple Thrift isset processor before any fields that have Thrift isset.
- Store the fully qualified names of enum types in DrgnParser - it already
  worked out this information anyway for naming the values and this is
  consistent with classes.
- Forward all enum template parameters under their input name under the
  assumption that they will all be policy type things like `IssetBitsetOption`.
  This could turn out to be wrong.

Test plan:
- CI (doesn't test thrift changes but covers other regressions)
- Updated Thrift enum tests for new format.
- `FILTER='OilIntegration.*' make test` - Thrift tests failed before, succeed
  after.

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.
