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.

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.

This change is fully backwards compatible with the old ContainerInfo
parser, as it is just adding new fields.
The old fields will continue to be used by legacy OICodeGen until that
is removed.
Also add a README to document the format.
