Subject: name our glib event sources to ease debugging

glib event sources can have a name, but it is not required.
Internal to glib, it is common to give them a name, see for example
https://git.io/JTZ8g .
This patch gives a name to each glib event source created in qtbase.

Task-number: QTBUG-84291
