Devtools: Simple timeline traversal and filtering

[turt2live]

Description

This probably doesn't need to be overly complicated. A reverse chronological list of buttons that show the event bodies would be fine (probably showing the event type/something useful on the button). Ideally the UI would also allow filtering, so a user could say "show events that are not m.room.message" or "only show events that contain 'im.vector' in the type", etc.

Would this not be better done by #5132?

[t3chguy]

oh I guess filtering, so would you want BOTH? :P

[turt2live]

#5132 is for within the timeline, this is for more of a deep-dive of the timeline within the dialog.

@turt2live, would it need to understand pagination or just show currently paginated events?

[turt2live]

It should probably understand pagination, although that doesn't really need to be MVP in my opinion. Although it's worth noting that I'd like to see the dialog in chronological order (newest first) which may throw pagination out the window as being way too complex.
