Issue number: resolves #29619
---------
<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->
<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->
## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
The `ionInput` emits for range even when the value hasn't changed. This
does not match our documentation. It should only emit when the value
changes (and continuously while the user is dragging the knob).
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Moved the emitter to the value watch function, to determine if the
value has changed.
- Added a test
-
## Does this introduce a breaking change?
- [ ] Yes
- [x] No
<!--
If this introduces a breaking change:
1. Describe the impact and migration path for existing applications
below.
2. Update the BREAKING.md file with the breaking change.
3. Add "BREAKING CHANGE: [...]" to the commit description when merging.
See

for more information.
-->
## Other information
<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->
How to test:
1. Navigate to the [range basic HTML
file](8ed08fcba5/core/src/components/range/test/basic/index.html (L77))
2. Add the following script
```
const ionicRanges = document.querySelectorAll('ion-range');
ionicRanges.forEach(range => {
range.addEventListener('ionInput', function(ev) {
console.log('ionInput', ev.currentTarget.value);
});
});
```
3. Navigate to the [range test
page](http://localhost:3333/src/components/range/test/basic)
4. Open the console
5. Move the single knob range (let go when you're done)
6. Verify that the value is shown in the console
7. Tap as close to the middle of the knob. The goal is to tap it without
the value moving.
8. Verify that the value does not show in the console
