[SD-486] allow requiring a suggestion in RplSearchBar

[lambry]

Issue: https://digital-vic.atlassian.net/browse/SD-486

What I did

• Implements the new map search bar changes, basically this just adds a prop to RplSearchBar that allows for a suggestion to be required for submission.
• Adds props to set iconPosition and showSubmitButton

This fixes a couple behavioral issues, for example currently pressing enter or the search button does nothing, unless you have already preformed a search then it will behave the same as the clear button, i.e. hitting enter or clicking search button deletes what you've typed in and performs a new search.
