Support builds with Conan

The recipe uses Conan's supported way to inherit from a given
base class via 'python_requires_extend'.

The qt-conan-common package implements a base class for Qt leaf
module recipes. The build steps in leaf modules are mostly identical
so it makes sense to put those in the base class.

Dependencies are read by the base class from the 'dependencies.yaml'
which is the same file the CI system uses.
