Use <comphelper/servicehelper.hxx> implementing XUnoTunnel part 1

The header got some changes:
1. Move UnoTunnelIdInit and isUnoTunnelId into 'comphelper' namespace
2. Rename UnoTunnelIdInit to UnoIdInit, as a precondition to replace
of uses of OImplementationId with it, including in XTypeProvider
3. Introduce convenience functions 'getSomething_cast' to cast between
sal_Int64 and object pointers uniformly.
4. Rename getUnoTunnelImplementation to getFromUnoTunnel, both to make
it a bit shorter, and to reflect its function better. Templatize it
to take also css::uno::Any for convenience.
5. Introduce getSomethingImpl, inspired by sw::UnoTunnelImpl; allow it
handle cases both with and without fallback to parent.
6. Adjust UNO3_GETIMPLEMENTATION_* macros

TODO (in separate commits):
- Drop sw::UnoTunnelImpl and sw::UnoTunnelGetImplementation
- Replace all uses of OImplementationId in core with UnoIdInit
- Deprecate OImplementationId in <cppuhelper/typeprovider.hxx>
- Change implementations of getSomething to use getSomethingImpl
- Revise uses of getSomething to use getFromUnoTunnel
