<!-- 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 current picker is only displayed as an overlay which makes it
impossible to use inline with the rest of the application. Additionally,
there are several bugs and missing features. For example, it is
impossible to know when the value of the picker column has changed using
public APIs. This is valuable for updating other columns in response to
that data.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Introduces `ion-picker` as an inline wheel picker component. The
overlay picker is still available using `ion-picker-legacy`.
- The implementation of this component resolves linked bugs. It also
resolves linked features by exposing an `ionChange` event for developers
to listen for.
## Does this introduce a breaking change?
- [ ] Yes
- [x] No
<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->
## Other information
<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->
