CMake: Check that QT_HOST_PATH is set when using the Qt toolchain
If a consumer wants to cross-compile a Qt app, they need to provide
the host Qt path location.
When building Qt in the CI we embed the Qt host path into the
generated CMake toolchain file for convenient building of other Qt
modules.
But once Qt is built, packaged and installed on a user's machine, most
likely the Qt host path will not be the same. In such a case, if the
user wants to use the convenience toolchain, they should explicitly
provide the Qt host path via the QT_HOST_PATH and
QT_HOST_PATH_CMAKE_DIR variables.
Show an error message if the values are not provided or don't exist
on the file system.
It's possible that in the future the Qt installer will patch the
toolchain file, or provide additional info, to point to the host
Qt installation so that the user doesn't have to do it manually.
But until that's done, a friendly error message is a good way to
inform the user what they should do.
