tdf#98955 hardware_concurrency not ideal for thread pools
A new static member getPreferredConcurrency added to
comphelper::ThreadPool to return a configurable max
number of threads.
By default the new function returns the hardware_concurrency
value provided by std::thread. When MAX_CONCURRENCY envar is
defined, the return value is limited to whatever is set there.
Three call-sites that used std::thread::hardware_concurrency
have been replaced with getPreferredConcurrency.
Unittests added to cover the functionality of the new member.
Unittests are capped to 4 threads.
