[clang][ExtractAPI] Stop dropping fields of nested anonymous record types when they aren't attached to variable declaration (#104600)

- Introduce primitives for removing records from `APISet` and managing
the record chain of `RecordContext`
- Detect nested anonymous record types and remove them from the `APISet`
after they have been fully traversed and transfer ownership of child
records to the parent context (if any)

[clang][ExtractAPI] Fix handling of anonymous TagDecls (#87772)

This changes the handling of anonymous TagDecls to the following rules:
- If the TagDecl is embedded in the declaration for some VarDecl (this
is the only possibility for RecordDecls), then pretend the child decls
belong to the VarDecl
- If it's an EnumDecl proceed as we did previously, i.e., embed it in
the enclosing DeclContext.

Additionally this fixes a few issues with declaration fragments not
consistently including "{ ... }" for anonymous TagDecls. To make testing
these additions easier this patch fixes some text declaration fragments
merging issues and updates tests accordingly.

[clang][ExtractAPI] Add ability to create multiple symbol graphs (#86676)

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.

[clang][ExtractAPI] Record availability information only for the target platform (#76823)

Currently, ExtractAPI provides availability information for all
platforms within a given domain. With this change, we narrow down the
output to include availability details only for the specified target
platform, so users can generate the symbol graph with only the
availability information they need, omitting information of the other
platforms.

This change reverts the functionality introduced in
[`57c9780`](https://github.com/llvm/llvm-project/commit/57c9780).

[clang][ExtractAPI] Add support for single symbol SGF and libclang support

This is mainly adding an entry point to `SymbolGraphSerializer` at
`serializeSingleSymbolSGF` and exposing the necessary data to make this
possible. Additionaly there are some changes to how symbol kinds and
path components are serialized to make the usage more ergonomic in
`serializeSingleSymbolSGF`.

On the libclang side this introduces APIs to:
- create an APISet from a TU
- dispose of an APISet
- query an APISet for a single symbol SGF for a given USR.
- generate a single symbol SGF for a given CXCursor, this only traverses
the necessary AST nodes to construct the result as oppposed as going
through the entire AST.
