Create Conan profile

Generate Conan profiles that can then be used with the SDK.
Task in qtbase generates profile that has all the architecture bits
and configure arguments in place. The profile added in the SDK phase
lets Conan recipes know how to use the SDK with the QT_CONFIGURE_MODULE
environment variable.
