Vojtech Bubnik ce020781d3 Refactored loading of Get/SetThreadDescription() on Windows:
These new API functions are not available on Windows 7 and on older Windows 10,
thus they are newly loaded dynamically and the functions using it retur
a bool indicating whether the functionality is supported or not.
Also the OSX variants that are not supported newly return false instead
of throwing an exception.

Fixes #4972 #4974
