This brings the NAND backup steps up to speed with the more up-to-date
Finalizing Setup prior to adding an automated script, which fixes
a few issues such as:
- missing step to copy `.bin.sha` from the SD card
- inconsistency where guide tells to copy `essential.exefs` without
extracting it first
* Add includes for ctrtransfer steps
- Region changing and CTRTransfer uses this
- Also split HBL open options, it is also used by finalizing setup
* Commonize NAND backup steps
Finalizing Setup won't use this include for the time being. But we
should use it for GM9 usage as well as Region Changing.
* Commonize GM9 SD format steps
Pages using this include:
- godmode9-usage
- move-emunand
* remove usage of is-powered-off, just do that in the main page
* always power off after NAND backup, it's trivial to get back in
Trying to explain what "unmounting" is to a user is going to be
confusing anyway
* Unconditionally don't set up an emuNAND, also remove usage of is-powered-off
* Fix rendering
