Summary:
tbv2: replace DB template param with Ctx
TreeBuilder v2 adds a DB template parameter to every function. This is used as
part of the static type to decide what type of DataBuffer is being used:
currently `BackInserterDataBuffer<std::vector<uint8_t>>` for OIL and it would
be `DataSegmentDataBuffer` for OID.
This change replaces the `DB` template parameter with a more general `Ctx`. Due
to issues with dependent naming it also adds a `using DB` to each `TypeHandler`
which has the same function as before. This allows us to add more "static
context" (typedefs and constants) to functions without changing this signature
again, because changing the signature of everything is a massive pain.
Currently this change achieves nothing because Ctx contains only DB in a static
wrapper. In the next change I'm going to pass a reference of type Ctx around to
add a "dynamic context" to invocations which will contain the pointer array. In
future we'll then be able to add either static or dynamic context without any
signature adjustments.

Summary:
Handlers were added in an intermediate form of tbv2 but those intermediate
forms have now been removed. Remove all the handlers to make grepping/find and
replaces easier across the types.

- CI
Summary:
Remove the now useless `handler` and adds the `traversal_func` and `processor`
entries for `std::list`. This type is a bit weird as most of our sequential
containers don't have any overhead on storing the element. I went for the same
approach we take for maps where we have a shared `[]` element covering the map
overhead and below that a `key` & `value`. As we only have a single element
under it which doesn't have a logical name I went for `*`.
Closes#315.

- Copied the relevant `std::vector` tests and updated the existing one.
Summary:
Currently there are two features between CodeGen v2 (TypeGraph) and TreeBuilder
v2. These are TypedDataSegment and TreeBuilderTypeChecking. Each of these
features currently has a full set of tests run in the CI and each have specific
exclusions.
Collapse these features into TreeBuilder v2. This allows for significantly
simplified testing as any OIL tests run under TreeBuilder v2 and any OID tests
run under TreeBuilder v1.
The reasoning behind this is I no longer intend to partially roll out this
feature. Full TreeBuilder v2 applies different conditions to containers than
the intermediate states, and writing these only to have them never deployed is
a waste of time.
Test Plan:
- it builds
- CI
Summary:
Adds the option for required features to container definitions. These cause the container not to be passed to `DrgnParser` if that feature is not enabled during code generation. The thrift isset type does not currently work with `tree-builder-v2` and only provides benefit with `capture-thrift-isset`. This change makes sure the container is ignored if it won't be useful, allowing code generation under `tree-builder-v2`.

Summary:
Previously on large types OIL would have problems with corrupting the `std::stack<exporter::inst::Inst>` that is passed to the processors. This change hides the implementation of the stack from the processors by wrapping the call to emplace in a `std::function` written by the non-generated code, which solves the test case I've seen for this crashing. It also allows us to easily change the stack implementation in future - I plan to change it to a `std::stack<T, std::vector<T>>` in a follow up.

Types within containers were previously named TODO. This sorts it out so
they're named as their most resolved type. The current implementation
skips Typedef names.
