DEV: Chat thread reply counter cache (#21050)

Browse Source 
Similar to 22a55ef0ce42823b860f2d3432e4d7f14a00752f,
this commit adds a replies_count to the Chat::Thread
table, which is updated every 15 minutes via PeriodicalUpdates.
This is done so the new thread indicator for the UI can
show the count without intense serializer queries, but
in future we likely want this to update more frequently.
