35493 Android software configurations API endpoints (#36096)

**Related issue:** Resolves #35493
Notes: 
- Currently this adds a new function `updateAndroidAppConfigurationTx`
that uses a passed transaction to stay consistent with how
uploading/editing vpp apps treats display names and custom icons.
- In some places configuration uses `omitempty` to use `json.RawMessage`
but avoid it being set to "null" in requests/respones.

## Testing

- [x] Added/updated automated tests
- [ ] Where appropriate, [automated tests simulate multiple hosts and
test for host
isolation](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/reference/patterns-backend.md#unit-testing)
(updates to one hosts's records do not affect another)

- [x] QA'd all new/changed functionality manually
- Can add an app with empty configuration {}
- Can delete the app, and configuration deletes as well
- Can't add app with invalid configuration
- "reason": "Couldn't update configuration. Only
\"managedConfiguration\" and \"workProfileWidgets\" are supported as
top-level keys."
- Can add an app with a good configuration
- Can edit app and change the configuration to something valid, invalid
gives error

For unreleased bug fixes in a release candidate, one of:

- [ ] Confirmed that the fix is not expected to adversely impact load
test results
- [ ] Alerted the release DRI if additional load testing is needed
