qmltc: generate code into namespaces

Generate code into namespaces to avoid clashes between qmltc-generated
and user code. Code generated by qmltc will by default be put in the
URI_OF_MODULE namespace, and will generate subnamespaces
to follow the module hierarchy if URI_OF_MODULE contains dots('.').

Also fix the test to use the new namespaces.

[ChangeLog][Qml][qmltc] The type compiler will generate C++-code into
a namespace by default. The  new default namespace is inferred from
the module's URI, where dots are interpreted as separating subnamespaces
from each other,
e.g., a type in module MyCompany.MyModule.Sub will be generated in the namespace
MyCompany::MyModule::Sub.
