create a class SolarMutexGuard to take a Guard on the SolarMutex

Most user of OGuard, use it to guard the SolarMutex.
using something like
vos::OGuard aGuard(Application::GetSolarMutex())

Which will now be written
vcl::SolarMutexGuard aGuard;

This will also, as a side effect remove the use of vos::Guard in many
sources, simplifying the migration out of ::vos
