Support builds with Conan

Provide conanfile.py recipe to support building this module
with Conan. The conanfile.py recipe inherits the main
functionality from base class located in qt-conan-common.git.

'qt-configure-module(.bat)' and cmake is used for the builds.

Dependencies (Conan requirements) are defined by the base
class implementation which reads those from the
'dependencies.yaml' which is also used by the Coin/CI.
