tdf#114025 framework: avoid deadlock between Desktop init ...

... and SolarMutex: the problem is that rtl::StaticWithArg will
first lock the implicit mutex of the C++11 static variable, and
then the SolarMutex.

So if one thread creates the Desktop singleton with SolarMutex
locked and another thread without SolarMutex locked, this can
deadlock.

If we use rtl_Instance directly with SolarMutex, then there is
still a static variable, but the SolarMutex will always be locked
first, preventing this deadlock.
