utilities: Split thread internal callback function

Browse Source 
__try is used in pthread_cleanup_push when CLEANUP_SEH is used as the
pthread cleanup model. That can't be used in functions with objects
that have destructors, so move it into a separate function.

Fixes a non-release build compile error on Windows. Regression was
introduced in 93d5b52df34c03a2ed859bba6e06fead3b875e70.
