Register C++ types declaratively

Adapt to the new way of registering C++ types. The types need to be
seen at compile time so that code can be generated that invokes them.

This patch:

- Adds QML_* macros where applicable.
- Adapts the build system files to the new way of registering modules.
- Splits up the QtQuick.Controls[.*].impl files into their own plugins,
  as we can only register one QML module per .pro file.
- Removes C++ type registration calls in every plugin.
- Moves private types from src/quickcontrols2/quickcontrols2.pro
  to src/quickcontrols2/impl/quickcontrols2-impl.pro. Some of these
  types need to be exposed to QML, but quickcontrols2.pro is already in
  use to declare the QtQuick.Controls import (and also provides the
  public C++ QQuickStyle API), and the new QML_IMPORT_NAME/VERSION
  syntax only allows one module per project. As some of the types that
  need to be exposed to QML are also referenced by some C++ code (e.g.
  tests, etc.), we just move all of the private types to the new
  library.

Follow-up patches will register the QML types declaratively.
