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:
Spin around our open/closed source checks. Previously we defined `OSS_ENABLE` in open source builds. This change defines `OI_META_INTERNAL` instead. This is nicer, as external users don't have to do anything special to get a working build.
Use this new macro to define a boolean constant in a new header `Portability.h`. This is inspired by Folly, and makes the internal build easier - definitions in Buck2 have to propagate up from a dependency instead of down from one. Annoyingly we can't use `if constexpr` for a lot of the previous `#ifdef` blocks as we conditionally include the headers. Longer term we could fix this by exposing a header interface but no source, allowing these to build but not be compiled in. For now I did something weird: I defined a function style macro in `Portability.h` based on the compile time macro. This forces you to have included `Portability.h` before using it to ensure the definition is everywhere. Open to feedback as I haven't seen anyone else do this.

Summary:
More moving code out of the `cea` subdirectory. This is moving the GOBS cache code which is contained in the 'internal' subdirectory. I'm hoping I get some auto generated diffs to push to GitHub for the third party source changes...

Summary: Add a second form for OIL AoT compilation which returns a `std::optional` instead of throwing. This is preferred if it's possible for the symbol to not be defined and you must not throw, instead preferring to handle the failure a different way. This still calls the throwing interface as that's what oilgen depends on, but makes sure the precondition is true first such that it won't throw.

Summary:
Extend the multiple config files system to OILGen, the piece it was originally designed for. This allows for specifying additional configs which say which keys of maps to capture.

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.
Github is currently extremely slow to load for me for some reason.
Due to that, I first thought that `cmake` is hung up, but tracing
that I realized it's waiting for minutes to download the sources
for tomlplusplus via FetchContent.
This patch enables progress reporting for FetchContent to make it
more obvious what's going on here.
Dummy and DummyAllocator nodes had been changed to use NodeIds, but
were still printed out in full when visited for a second time.
[[nodiscard]] prevents future bugs of this type by turning them into
compilation errors.
Example of the now-fixed bug:
[1] Container: std::map<int32_t, int32_t, DummySizedOperator<0, 0, 8>, std::allocator<std::pair<int32_t const, int32_t>>>
