ChoiceGroups no longer have hardcoded margins. A new ChoiceGroupList holds them,
with padding and spacing that give the same look as before. Settings tabs, developer
tools, the two-pane settings columns, the pause menu and the rest put their groups in
one, and a few screens adjust its padding and spacing to their layout.
Also add the two groups in the remote disc streaming settings that were created but
never added, and make the settings search look inside groups: it only checked a tab's
direct children, so with ChoiceGroups a filter hid everything.

The checkbox array was reloaded from the config on every view creation,
but only saved when a popup closed or the screen finished. Rotating the
device reverted the choices. Also stop leaking a handler per button on
each rebuild.

CustomButtonMappingScreen indexes customKeyImages[36] and customKeyShapes[11] with
values read straight from the ini, and it's reachable from the main menu - so
neither GamepadEmu nor TouchControlLayoutScreen, which both sanitize first, need
have run. Those two had the same fixup copy-pasted; hoisted it into a Sanitize()
next to the tables and called it from all three.
