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
Not all containers have 8-byte alignment, so if we want to avoid lots of
manual logic for calculating container alignment on a case-by-case
basis, we must calculate alignment from the member variables before the
Class nodes have been replaced by Container nodes.
Leave it to the new mutator pass IdentifyContainers to replace Class
nodes with Container nodes where appropriate.
This will allow us to run passes over the type graph before identifying
containers, and therefore before we have lost information about the
internal details of the container (e.g. alignment of member variables).
For the containers which are allowed to be declared with incomplete
types, it is only the contained types which are allowed to be
incomplete. Other template parameters (e.g. allocators) must always be
defined before use.
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 OID/OIL required exactly one configuration file. This change makes it so you can supply 0 or more configuration files. 0 is useful if you have pre-generated the cache or use some sort of remote generation system. 1 is useful for the common case, where you have a configuration file that describes your entire source and use just that. More are useful if you have supplemental bits of config you wish to apply/override - see the changes to the integration test framework where we do exactly this.
Test Plan:
This isn't super well tested. It works for the test cases which add features via the config or enable `codegen.ignore`.

Lots of places rely on reference stability of ContainerInfo objects
(CodeGen's deduplication, Container nodes' containerInfo_ member).
In the key capture work, we need to be able to append to this list,
which would invalidate references before this change.
We only want to do the extra work if it's explicitly requested.
chaseRawPointers is already explicitly requested whenever it's needed
and readEnumValues currently isn't needed at all.
Summary:
Update to clang-15 compiler and libraries as clang-12 is ancient.
The changes to oilgen are necessary because the new internal toolchain is being more picky about linking PIC to PIC. In certain modes we build with PIC, but try to link a non-PIC oilgen artifact. Add the ability to build the oilgen artifacts with PIC which sorts this.
