[SD-144] fix map fullscreen button

[lambry]

Issue: https://digital-vic.atlassian.net/browse/SD-144

What I did

• The close button (i.e. cross icon) wasn't displaying when the map goes full screen
• Also requestFullscreen is, to quote MDN "Only available on iPad, not on iPhone.", so now we don't display the full screen button if it won't work i.e. on iPhones.

How to test

• Ripple 2.14.0 (current behaviour) https://www.develop.police.vic.gov.au/police-station-location?activeTab=map
• Branch with this update https://app.pr-482.vicpol-vic-gov-au.sdp4.sdp.vic.gov.au/police-station-location?activeTab=map
