…type (#34521)

Some components accept a union of a ref callback function or ref object.
In this case we may infer the type as a function due to the presence of
invoking the ref callback function. In that case, we currently report a
"Hint: name `fooRef` as "ref" or with a "-Ref" suffix..." even though
the variable is already named appropriately — the problem is that we
inferred a non-ref type. So here we check the type and don't report this
hint if we inferred another type.

## Summary

<!--
Explain the **motivation** for making this change. What existing problem
does the pull request solve?
--> The React Compiler rejected a default parameter that contains a
TSInstantiationExpression with the todo message that the expression
cannot be safely reordered. This change teaches the reorder check in
BuildHIR.ts to treat TSInstantiationExpression as reorderable. This is
safe because TypeScript instantiation only affects types and is erased
at runtime, so it has no side effects and does not change semantics.

## How did you test this change?

```
Set-Content testfilter.txt 'ts-instantiation-default-param'

yarn test --filter --update

yarn test --filter
```

Stacked on #34510.

The "Commit" phase for a View Transition starts before the snapshot
phase (before mutation) and then stretches into the async gap of
`startViewTransition`, encompasses the mutation phase inside of its
update callback and finally the layout phase.

However, between the mutation phase and the layout phase we may suspend
the start of the view transition on fonts and/or images. In that case we
now split the Commit phase into first one before we suspend and then we
log "Waiting for Images and/or Fonts" and then another Commit phase
around the layout effects.

In an upstack PR, I need `getDebugInfo` in another test file, so I'm
moving it to `internal-test-utils` so it can be shared.

## Summary

Made many small changes to the compiler playground to improve user
experience. Removed any "Loading" indicators that would flash in before
a component would finish loading in. Additionally, before users would
see the "Show Internals" button toggling from false to true if they had
set it at true previously. I was able to refactor the URL/local storage
loading so that the `Store` would be fully initialized before the
components would load in.

Attempted to integrate `<Activity>` into showing/hiding these different
editors, but the current state of [monaco
editors](https://github.com/suren-atoyan/monaco-react) does not allow
for this. I created an issue for them to address:
suren-atoyan/monaco-react#753

Added a debounce to the config editor so every key type wouldn't cause
the output panel to respond instantly. Users can type for 500 ms before
an error is thrown at them.

so blurry):

Seems like this was missed in
#31313

If we don't handle Lazy types specifically in `renderDebugModel`, all of
their properties will be emitted using `renderDebugModel` as well. This
also includes its `_debugInfo` property, if the Lazy comes from the
Flight client. That array might contain objects that are deduped, and
resolving those references in the client can cause runtime errors, e.g.:

```
TypeError: Cannot read properties of undefined (reading '$$typeof')
```

This happened specifically when an "RSC stream" debug info entry, coming
from the Flight client through IO tracking, was emitted and its
`debugTask` property was deduped, which couldn't be resolved in the
client.

To avoid actually initializing a lazy causing a side-effect, we make
some assumptions about the structure of its payload, and only emit
resolved or rejected values, otherwise we emit a halted chunk.
