Summary:
## Rationale
- AsyncDevSupportManager.loadSplitBundleFromServer() is an override of DevSupportManager.loadSplitBundleFromServer(), which is used by the bridge. However, AsyncDevSupportManager.loadJSBundleFromServer() has no bridge analogue. This is confusing: Are the methods in AsyncDevSupportManager Venice overrides for bridge related methods? It's easy to think yes, but the answer is no.
- AsyncDevSupportManager.loadJSBundleFromServer() is an additional layer of indirection that provides very little value: all it does it create the JSBundleLoader, and call onReactContextCreated. However, it does so in 11 lines of very confusing code.
A discussion we don't have to have now: Inheritance hierarchies are very difficult to understand and de-tangle. So, instead of using inheritance to make DevSupportManager work with Venice (via AsyncDevSupportManager), should we just refactor DevSupportManager so that it can be customized to work with Venice?

Summary:
~Scheduler and ~SurfaceHandler both contain react_native_asserts that trip whenever we reload React Native with Fabric enabled. These asserts trip because of a memory leak in Fabric. These asserts do not run in production. We should fix the memory leak before re-enabling these assertions.

[Internal] - Update Switch to allow injected implementations
## General understanding of the component
The main flow of Switch is pretty straightforward, basically passing the props to the respective native component which uses the platform switch views on Android / iOS
The interesting parts of Switch is the fact that it's a controlled component -- meaning that this component sees the JS value prop as the source of truth about the state of this component and any time the native value of the switch is out of sync with the JS value prop, we send a command `setNativeValue` to keep those in sync.
The problems I ran into:
* Keeping native and JS in sync
* Switch skips animation occassionally on iOS simulator
## How we keep native and JS in sync
By construction, the native value of the component should be the same as JS value. Then, we know the native value has changed whenever the callback `handleChange` has been fired.
**Before**
In the handleChange callback, we'd set an [instance variable `lastNativeValue` with the updated value](https://fburl.com/diffusion/nangxzoh) and force update. Then, in `componentDidUpdate`, we'd send the native commands if we determine that `lastNativeValue` and the `value` prop were out of sync.
**After**
For our modern implementation, we store the value of the switch as reported by `handleChange` and check it against the `props.value` of the switch. If they are out of sync then we will update the native switch via the switch command.
**Why is `native` an object?**
We need to run the `useLayoutEffect` every time `handleChange` is called independent of the value of the switch.
**Why not move the logic of dispatching commands to `handleChange`?**?
This would change behavior from old implementation where we would call `onChange` handlers and then re-render. Additionally, the logic to run the native commands were on `componentDidUpdate` which would've run when any prop changed. We can simplify this down to caring only when `props.value` updates.
## Unsolved, existing issue: Switches skip animation occasionally
* This occurs both in the modern and old versions of Switch and I've only seen this on iOS simulators. It occurs most frequently in the "events" example where two switches' values are synced and most often the first transition after we navigate to the example surface. I have not been able to reproduce this behavior on device.
* Something must be triggering a re-render in the middle of native's animation..

The current test failures don't include the values passed to `EXPECT` which makes it difficult to understand if the test ended earlier or later then expected.
```
Failure: Value of: (commitDuration >= 1000 - threshold) && (commitDuration <= 1000 + threshold)

```
This diff uses the gtest `EXPECT_NEAR` to get exception messages including the delta:
```
Failure: The difference between telemetryDurationToMilliseconds(telemetry.getTextMeasureTime()) and 600 is 153, which exceeds threshold, where
telemetryDurationToMilliseconds(telemetry.getTextMeasureTime()) evaluates to 753,
600 evaluates to 600, and
threshold evaluates to 70.

This doesn't change the test's flakiness because of how sleep is implemented.

3. Return sane defaults so that prod cases don't crash, and don't return totally garbage data.

Summary:
If an invalid color is supplied to a native component that expects `Array<ColorValue>`, it is currently possible to produce an array that contains null or undefined elements. This is problematic because the native component may not know what to do with the null or undefined value.
This changes `processColorArray` to always return an array with valid color values. Any invalid color values will fallback to being transparent black, `0x00000000`.
