Make the icons changeable

[oividioscaeremos]

Is your feature request related to a problem? Please describe.
Currently, the clear icon is literally the letter x with some styling going on around it.

Describe the solution you'd like
I would like to have an option to change the clear icon. At the very least, there shouldn't be a literal character there that makes it very hard to change. (I had to clear the letter x and then style a custom icon via JS and not a big fan of this solution since it requires a re-do every time the clear icon is clicked on and some value is entered.)

Changing the dropdown icon was also tricky, so if both are re-designed to get changed via an <ng-content> it would be good.

Describe alternatives you've considered
I described above how I overcame this issue.
