[3.12] gh-104812: Run Pending Calls in any Thread (gh-104813) (gh-105752)

Browse source 
For a while now, pending calls only run in the main thread (in the main interpreter).  This PR changes things to allow any thread run a pending call, unless the pending call was explicitly added for the main thread to run.
(cherry picked from commit 757b402)
