All symbols are private (as in the API descriptor) if the library level
is more restricted than `LibraryLevel::API`.

Now that API descriptions are emitted during module build jobs when
`-emit-api-descriptor-path` is specified and the build system has been updated
to pass that flag when the output is needed, the `swift-api-extract` frontend
alias is no longer used. Delete it and the tests that were specific to invoking
`swift-api-extract`.
Resolves rdar://116537394.
This now specifies a category name that’s used in TBDGen, IRGen, and PrintAsClang. There are also now category name conflict diagnostics; these subsume some @implementation diagnostics.
(It turns out there was already a check for @objc(CustomName) to make sure it wasn’t a selector!)
Instead, use the `%validate-json` lit substitution to validate and format the
API descriptor file before running it through FileCheck. This allows us to
avoid needing to introduce a dedicated frontend option just to control whether
the output of -emit-api-descriptor is pretty printed.
Make the changes to APIGenRecorder that are necessary to make it capable of
emitting API descriptors during -emit-module jobs. The output in this mode
differs from the output when run on an existing module in a couple of important
ways:
- The value for the `file` key in the descriptor JSON is now the path to the
source file that defines the declaration responsible for the symbol. In
`swift-api-extract` mode, the value for this key is the path to the module or
swiftinterface which is unavailable during an -emit-module job since the module
is usually not being emitted to its final installed location.
- Some additional symbols may be included in the API descriptor JSON because
more of the AST is available when emitting the module.

Emit Objective-C Categories for extensions that have the @objc attribute
directly (or indirectly via one of its methods, subscripts, etc) attached.
Also associate and emit all methods for that category into the API JSON file.
This fixes rdar://94734748.
