Stacked on #30625 and #30657.

This ensures that we only create instances during the commit reconciliation and that we don't create unnecessary instances for things that are filtered or not mounted. This ensures that we also can rely on the reconciliation to do all the clean up. Now everything is created and deleted as a pair in the same pass.

Previously we were including unfiltered components in the owner stack which probably doesn't make sense since you're intending to filter them everywhere presumably. However, it also means that those links were broken since you can't link into owners that don't exist in the parent tree.

The main complication is the component filters. It relied on not unmounting the old instances. I had to update some tests that asserted on ids that are now shifted.

For warnings/errors tracking I now restore them back into the pending set when they unmount. Basically it puts them back into their "pre-commit" state. That way when they remount they’re still there.

For restoring the current selection I use the tracked path mechanism instead of relying on the id being unchanged. This is better anyway because if you filter out the currently selected item it's better to select the nearest match instead of just losing the selection.

I couldn’t figure out what this check was needed for. It’s not covered by any tests nor comments in the original PR. Some of the HMR issues that the PR refers to don’t have repros so it might have just been throwing things against the wall to see what sticks.

But this doesn’t make sense to me because if a fiber is going to get remounted it always a new fiber instance anyway which is disconnected and gets a new id so the old one does need to be cleaned up.

@sebmarkbage
Move instances creation to explicitly only happen during reconciliation
acdbf96 
So we don't end up with hanging other instances.
@sebmarkbage
Don't conditionally check _debugNeedsRemount
93b3e72 
I don't think this ever made sense because this flag is only active on the
fiber that was deleted. There will be a new one that gets a new id anyway.
So this must have just leaked the old fibers.
@sebmarkbage
Remove the notion of simulated unmounts
341ef14 
We don't need this distinction because we're not doing them in any reverse
order.
@sebmarkbage
Unmount and remount root fully when updating filters
8c9613c 
This means warnings/errors get reset.
@sebmarkbage
Don't include filtered fibers in the owners list
a13f095 
These don't have any instances but arguably they shouldn't be included in
the list.
@sebmarkbage
Restore pending errors/warnings after unmount
2929c49 
We don't delete the errors until they've been shown in an unfiltered fiber.

Instead rely on GC to clean up the pending errors/warnings using a weakmap.
@sebmarkbage
Update IDs in snapshots
a76ce18 
If we remount due to filters we've now increased ids (inspectedElement).

However we also avoid creating ids for filtered components (profilingCache).
@sebmarkbage
Restore selection from last inspected when updating component filters
11cfe0d 
This uses the tracked path to select the nearest one instead of relying
on a specific id still existing since it'll be remounted. It might get
filtered so it's best to select nearest path anyway.

I need to move the test into inspected element since we rely on the inspected
element being changed to track the current selected path.
