Swift's Windows installer is missing the features.json file for docc and clang

[jakepetroules]

Description

I'd expect "features.json" to be present in the following directories:

%LOCALAPPDATA%\Programs\Swift\Toolchains\6.0.0+Asserts\usr\share\clang
%LOCALAPPDATA%\Programs\Swift\Toolchains\6.0.0+Asserts\usr\share\docc

Currently, it is only present in

%LOCALAPPDATA%\Programs\Swift\Toolchains\6.0.0+Asserts\usr\share\swift

DocC is not yet available due to this outstanding change: swiftlang/swift-docc#668

Adding in features.json should just be a matter of updating the manifest in https://github.com/apple/swift-installer-scripts
