## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
The Angular implementation of `ion-tabs` does not support conditional
binding the `slot` property on `ion-tab-bar` or assigning a variable as
the slot.
For example, this usage is invalid:
```html
<ion-tabs>
<ion-tab-bar [slot]="slot"></ion-tab-bar>
</ion-tabs>
```
This occurs because `ng-content` only supports static content
projection. It is not intended for scenarios where the content can be
relocated or conditionally rendered.
An example of static content projection would be:
```html
<ion-tabs>
<ion-tab-bar slot="top"></ion-tab-bar>
</ion-tabs>
```
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- `ion-tabs` supports conditional slot bindings or a slot that is bound
to a variable in Angular.
The revised implementation relocates the tab bar in the `ion-tabs`
template, based on it's current slot attribute. The implementation
checks the tab bar slot whenever the content changes.

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
The counter for incrementing the `id` and `z-index` of an overlay is
incremented whenever the `connectedCallback` is fired for an overlay.
When an overlay is presented and/or conditionally rendered, the overlay
`id` can increment by `n+2` instead of `n+1`.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Increments all overlay ids consistently
- Removes legacy `ion-modal-{id}` and `ion-popover-{id}` logic
- Adds unit tests for the id behavior
- Tests are split up into separate files so that the counter is always
starting from `0`
- Adds an integration test with the Angular test app to verify
conditional rendering behavior

BREAKING CHANGE:
Angular v14 is now required to use `@ionic/angular` and `@ionic/angular-server`. Upgrade your project to Angular v14 by following the [Angular v14 update guide](https://update.angular.io/?l=3&v=13.0-14.0).
The dev-preview `environmentInjector` property has been removed from `ion-tabs` and `ion-router-outlet`. Standalone component routing is now available without additional custom configuration. Remove the `environmentInjector` property from your `ion-tabs` and `ion-router-outlet` components.
BREAKING CHANGE:
`ionChange` is no longer emitted when the `value` of `ion-select` is modified externally. `ionChange` is only emitted from user committed changes, such as confirming a selected option in the select's overlay.
BREAKING CHANGE:
`ionChange` is no longer emitted when the `checked` property of `ion-checkbox` is modified externally. `ionChange` is only emitted from user committed changes, such as clicking or tapping the checkbox.
