[master] Fix requisite performance issues and aggregation

[bdrx312]

What does this PR do?

• add install of networkx
• fix aggregate to properly work with requisites
• fix requisite checking to not be exponential
• fix pkg aggregate to work when multiple states specify the same package; added some type hints to state.py and tagify in event.py to make the code easier to follow

What issues does this PR fix or reference?

Fixes: #8210, #47154, #59123, #62439, #65304

Previous Behavior

Applying states with many requisites took exponential time by the number of states with requisites.
Aggregating states did not honor requisites correctly.

New Behavior

Applying many states with requisites is no longer exponential.
Aggregating states now correctly honors requisites.
