feat(profiling) add thread names

[realFlowControl]

Description

This PR will add a thread name label to collected samples. In most cases a dedicated thread name is either not set or even if it is not helpful. For NTS PHP we do just use the SAPI name as the thread name, this seems helpful. For ZTS we currently only collect a thread name for FrankenPHP as it sets meaningful names.
Additional notes:

• on Darwin a thread name might be empty if not set
• on Linux a thread name is the process name if not explicitly set (which is the case for most)

In the future we should try and detect Apache and parallel threads and name them accordingly.
