2060a0491e CodeGen v2: Enable independent running without CodeGen v1

structs, suitable for use in OICache and TreeBuilder.

8e8db376d8 OICodeGen: Respect ContainerInfo::requiredFeatures
CodeGen v1 and CodeGen v2 must be in sync in order for CodeGen v2 and
TreeBuilder v1 to be compatible. This change updates CodeGen v1 to use
the same set of containers as CodeGen v2.

This specifically fixes "-ftype-graph -Ftree-builder-v2 -Fcapture-thrift-isset"
for Thrift types.

The integration test "thrift_isset_no_capture" covers this, but this bug
was missed as the Thrift tests do not run in CI.

3871d92abb collapse TreeBuilderV2 features
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

4c6f232766 containers: add required features (#374)
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`.


Test Plan: - CI

04715e2015 TypeGraph: Create dummy containers
These represent types which don't store any interesting data for us to
measure, but which are required by a real container so can not be
replaced with our own generated class types.

std::allocator often has bad DWARF, so it must be replaced after the
DWARF is fixed up in Flattener. The others could be replaced earlier in
the transformation process if desired, but I've left them all together
for simplicity for now.

This fixes the folly::fbstring tests.
