Fix a memory leak when using non-wx threads

Browse source 
The wxThreadSpecificInfo object created by wxThreadSpecificInfo::Get()
was only released by the wxThreadInternal's cleanup, which meant that it
was leaked if wxThreadSpecificInfo::Get() was called by a thread not
created by wxThread, e.g. when using std::async or std::thread.

Fix this by simply using C++11 thread_local and removing the entire
wxThreadSpecificInfo machinery entirely.

See #23535.

Closes #23543.
