* Load pending state attributes and event data ids at startup
Since we queue all events to be processed after startup
we can have a thundering herd of queries to prime the
LRUs of event data and state attributes ids. Since we
know we are about to process a chunk of events we can
fetch all the ids in two queries
* lru
* fix hang
* Fix recorder LRU being destroyed if event session is reopened
We would clear the LRU in _close_event_session but
it would never get replaced with an LRU again so
it would leak memory if the event session is reopened

* Mark PostgreSQL range select as fast
Currently we were using the slow range select workaround for
PostgreSQL that was original developed for MariaDB but
its actually slower on PostgreSQ

* Adjust size of recorder LRU based on number of entities
If there are a large number of entities the cache would
get thrashed as there were more state attributes being
recorded than the size of the cache. This meant we had
to go back to the database to do lookups frequently when
an instance has more than 2048 entities that change
frequently

* do not actually record 4096 states

Dropping the database after this test will fail on
MySQL and hang forever because it causes an InnoDB deadlock
```
| 2042 | root | localhost:52698 | NULL | Query | 41 | Waiting for table metadata lock | DROP DATABASE `homeassistant-test` | 0.000 |
```
This test was recently enabled on MySQL in
https://github.com/home-assistant/core/pull/87753
Since it the migration is still in progress in the background
when the test ends, it causes deadlock with InnoDB when its dropped
out from under it
Fix recorder run history during schema migration
RunHistory.get and RunHistory.current can be called before
RunHistory.start. We need to return a RecorderRuns object
with the recording_start time that will be used when start
it called to ensure history queries still work as expected.

```
recorder/test_init.py:251: SAWarning: SELECT statement has a cartesian product between FROM element(s) "states" and FROM element "state_attributes". Apply join condition(s) between each element to resolve.
```
* Speed up comparing State and Event objects
Use default python implementation for State and Event __hash__ and __eq__
The default implementation compared based on the id() of the object
which is effectively what we want here anyways. These overrides are
left over from the days when these used to be attrs objects
By avoiding implementing these ourselves all of the equality checks
can happen in native code
* tweak
* adjust tests
* write out some more
* fix test to not compare objects
* more test fixes
* more test fixes
* correct stats tests
* fix more tests
* fix more tests
* update sensor recorder tests
