core: maintain a single table with event source priorities

It's hard to oversee the assigned processing priorities of the various
event sources we have. Let's unify them in a table (an enum), where we
can have a single consisten look at them, and then reference the table
entries by expressive symbols.

This doesn#t change behaviour in any way, it just gives each priority a
nice label, but doesn't change any of the priorities.

Prompted by: #30799
