Description of changes

Exposed the ability to set the keyboard return type for the SearchBar component.

Binary change

(how is our binary size impacted -- see https://github.com/microsoft/fluentui-apple/wiki/Size-Comparison)

Verification

Added an example to the test app and observed the return key type was being set successfully. By default for the search bar the return key type is "search". When we override it to "done" it appears as "done" in the keyboard.

Visual Verification

Before (Default)	After (Overridden as "done")
