plugin-manager: new methods to check for ongoing port support operations

The new mm_plugin_manager_is_finding_port_support() allows to check whether the
Plugin Manager is looking for support in a specific port.

The new mm_plugin_manager_is_checking_device_support() allows to check whether
the Plugin Manager is looking for support in any port of a given device.
