Add "Delete All Saves" QoL Feature.

*Added "Enable Delete All Saves" Checkbox.
*Added "Delete All Saves" Button

Both are in "Settings -> General -> General Settings" under the
"Open App Files Folder" button.

The "Enable Delete All Saves" Checkbox when checked enables the
"Delete All Saves" Button.It is uncheck by default.

The purpose for the "Enable Delete All Saves" checkbox is to prevent the
possibility of accidentally pressing the "Delete All Saves" Button by
mistake.

When the "Delete All Saves" Button is pressed it will delete all 3 save
files and resets SoH and then disables itself by turning off
"Enable Delete All Saves" Checkbox.

The Reasoning for this Qol is to have a quick way to
delete all saves instead of deleting each file using the in-game
file menu(takes a while took 30 actions to delete all 3 files)
or navigating the App file folder(Would require closing Soh, the
reset button doesn't clear the files slots in-game
if files are deleted outside of SoH.).
