Remove unnecessary code in /widget.

- Remove numerous blocklist entries that no longer apply.
- Remove CanComputeVirtualKeyCodeFromScanCode(), because it's always true.
- Remove ShowXP{Folder,File}Picker(), since we have native pickers on supported Windows versions.
- Remove the config.trim_on_minimize preference, which is pointless on NT6+ and will just cause problems if used.

Tag #22.
