Extension SGFs require the module system to be enabled in order to discover which module defines the extended external type.
This patch ensures the following:
- Associate symbols with their top level module name, and that only top level modules are considered as modules for emitting extension SGFs.
- Ensure we don't drop macro definitions that came from a submodule. To this end look at all defined macros in `PPCalbacks::EndOfMainFile` instead of relying on `PPCallbacks::MacroDefined` being called to detect a macro definition.
Reenables b31414bf4f9898f7817a9fcf8a91f62ec26f3eaf.
Also adds a new warning for missing `--symbol-graph-dir` arg when
`--emit-extension-symbol-graphs` is provided. This also reverts the
commit that removed.
This extends ExtractAPI to take into account symbols defined in categories to types defined in an external module.
This introduces 2 new command line flags, `--symbol-graph-dir=DIR` and `--emit-extension-symbol-graphs`, when used together this generates additional symbol graph files at `DIR/ExtendedModule@ProductName.symbols.json` for each external module that is extended in this way.
Additionally this makes some cleanups to tests to make them more resilient and cleans up the `APISet` data structure.
Other implementations of the symbol graph format use zero-based indices
for source locations, which causes problems when combined with clang's
current one-based indices. This commit sets ExtractAPI's symbol graph
output to use zero-based indices to align with other implementations.

This includes:
- replacing "relationhips" with "relationships"
- emitting the "pathComponents" property on symbols
- emitting the "accessLevel" property on symbols

To achieve this we hook into the preprocessor during the
ExtractAPIAction and record definitions for macros that don't get
undefined during preprocessing.
