[ExtractAPI] reorder the module names in extension symbol graph file names (#119925)

Resolves rdar://140298287

ExtractAPI's support for printing Objective-C category extensions from
other modules emits symbol graphs with an
`ExtendedModule@HostModule.symbols.json`. However, this is backwards
from existing symbol graph practices, causing issues when these symbol
graphs are consumed alongside symbol graphs generated with other tools
like Swift. This PR flips the naming scheme to be in line with existing
symbol graph tooling.

[clang][ExtractAPI] Fix quirks in interaction with submodules (#105868)

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.

[clang][NFC] fix name lookup for llvm::json::Value in SymbolGraphSerializer (#94511)

This code uses namespaces `llvm` and `llvm::json`. However, we have both

declare or include `llvm::Value`, the lookup becomes ambiguous.

Fixing this by qualifying the `Value` type.

[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).
