Make push rules use proper structures. (#13522)

Browse Source 
This improves load times for push rules:

| Version              | Time per user | Time for 1k users | 
| -------------------- | ------------- | ----------------- |
| Before               |       138 µs  |             138ms |
| Now (with custom)    |       2.11 µs |            2.11ms |
| Now (without custom) |       49.7 ns |           0.05 ms |

This therefore has a large impact on send times for rooms
with large numbers of local users in the room.

"""
Push rules is the system used to determine which events trigger a push (and a
bump in notification counts).
from synapse.push.rulekinds import PRIORITY_CLASS_INVERSE_MAP, PRIORITY_CLASS_MAP
This consists of a list of "push rules" for each user, where a push rule is a
pair of "conditions" and "actions". When a user receives an event Synapse
iterates over the list of push rules until it finds one where all the conditions
match the event, at which point "actions" describe the outcome (e.g. notify,
highlight, etc).
Push rules are split up into 5 different "kinds" (aka "priority classes"), which
are run in order:
1. Override — highest priority rules, e.g. always ignore notices
2. Content — content specific rules, e.g. @ notifications
3. Room — per room rules, e.g. enable/disable notifications for all messages
in a room
4. Sender — per sender rules, e.g. never notify for messages from a given
user
5. Underride — the lowest priority "default" rules, e.g. notify for every
message.
The set of "base rules" are the list of rules that every user has by default. A
user can modify their copy of the push rules in one of three ways:
1. Adding a new push rule of a certain kind
2. Changing the actions of a base rule
3. Enabling/disabling a base rule.
The base rules are split into whether they come before or after a particular
kind, so the order of push rule evaluation would be: base rules for before
"override" kind, user defined "override" rules, base rules after "override"
kind, etc, etc.
