[nce, fs] tico support, fix FS bug that would nuke entire 'switch' folder (#4086)

Contains the minimal set of functionalities to allow tico installer succeed, and tico work normally EXCEPT for game launching (which me or someone else will investigate later)

First three commits are from PR 4012.

The other six, kinda dizzy to explain each one. All were implemented based on tico source, switchbrew and libnx.
Hopefully the commit messages will do.
