altTab: Only calculate iconSize once

Browse Source 
Right now, _setIconSize() calculates the icon size everytime the
preferred height of AppSwitcher is calculated, which happens quite
often.

Reduce the perfomance impact by only calculating the icon size once.
This has the added benefit of preventing unexpected changes to the icon
sizes while the switcher is open.
