WinRT: keyboard VirtualKey translation improvements from Sylvain Becker

Browse source 
Changes included:
- adding support for a few, additional, VirtualKey constants
- removing accesses to 'windows_scancode_table', as the table's contents
don't line up with WinRT virtual keys.  Using Windows older VK_* constants
may, however, be a good alternative in a future update.
