MDEV-27943 Reduce overhead of attaching THD to OS thread, in threadpoolbb-10.6-wlad
Avoid relatively expensive THD::store_globals() for every query in the
threadpool. Use a lighter version instead, that only resets some thread
local storage variables(THD, mysys, PSI), avoids some calculationms
and caches syscall gettid (Linux only) in a thread_local variable.
Also simplify Worker_context use, with RAII.
