[vcpkg format-manifest] Add convert-control flag (#12471)

* [vcpkg format-manifest] initial convert-control attempt

TODO: manifest comments! we should keep $directives

* Finalize x-format-manifest

First, fix Json::parse -- "\c", for any c, was incorrectly parsed.
It would emit the escaped character, and then parse the character, so
that `\b` would give you { '\b', 'b' }.

Second, canonicalize source paragraphs as we're parsing them. This found
an error in qt5 -- The `declarative` feature was listed twice, and we
now catch it, so I removed the second paragraph.

Add PlatformExpression::complexity to allow ordering platform
expressions in a somewhat reasonable way.

Notes:
  - We allow `all_modules` as a feature name for back-compat with
    paraview
  - In order to actually convert CONTROL to vcpkg.json, we'd need to
    rename the qt5 `default` feature.
  - We need to add support for $directives in x-format-manifest
