[BUG] Installing title directly from cart should perform validity checks first

[Wack0]

GM9 can install titles directly from a cart.

However, cart data can bitrot, so when installing from cart, hash/etc checks should be performed first to ensure the validity of the contents being installed.

This could also be done for all contents originally from a cart (NCSD, NCCH with exheader flag SDApplication bit unset), but I think this wouldn't be required (it's easier to externally check existing dumps) and I just mention this for completeness.
