Move yield mutex handling into SalInstance

After the refectoring in commit 4c93de2c921b ("merge
GenericSolarMutex and SolarMutex"), there is no more need to
prevent instantiation of comphelper::SolarMutex objects.

Since every VCL backend implements the yield mutex management in
the same way, we can move the general implementation into the
SalInstance.

While at it use std::unique_ptr for the yield mutex on Mac and
Windows platforms.
