feat: Add 'picker' interface for ion-select component

[zamora95]

Feature Request

Ionic version:

[x] 4.x
[x] 5.x

Describe the Feature Request

It would be helpful if it were possible to use ion-picker as an interface for ion-select

Describe Preferred Solution

You could add a 4th value: (picker) for 'interface' property of ion-select.
ion-select-option could work as options for one-column picker.
If the picker options were in the template it would be easier apply Angular and custom pipes. At the same time, we could name the control to include into a form.

Related Code

This is an extract from one of my projects, changing the 'interface' property value:

<form #f="ngForm" (ngSubmit)="onSubmit(f)">
  <ion-select name="newScheduled" interface="picker" cancelText="Cancelar" okText="Aceptar">
    <ion-select-option *ngFor="maint of maintenances" [value]="maint">{{ maint.start | date: 'shortDate' }} {{ maint.start | date: 'shortTime'}} - {{ maint.end | shortTime }}</ion-select-option>
    <ion-select-option>Other schedule</ion-select-option>
  </ion-select>
</form>

I would like it to look like this

Additional Context

I find it hard to imagine how we could pass options for two or more columns, but it would be a great addition too.

for now - why don't you fake it, use an ion-item, stick an icon with the down arrow in the end slot.
Then on click, show your picker interface programmatically.
Set the ion-item label to whatever your choice is.
