CMakeProjectManager: Support for multi-config generators

CMake has multi-config generators like:

  * Visual Studio
  * Xcode
  * Ninja Multi-Config

The first two have different special targets for "all", "install",
"package", "test" namely: "ALL_BUILD", "INSTALL", "PACKAGE",
"RUN_TESTS".

All of them need to get the build type passed via "--config <build-
type>" and not via "CMAKE_BUILD_TYPE".

The multi-config generators will use only one build directory.

Fixes: QTCREATORBUG-24984
