core: use the 12 GiB layout and auto-stub IPC for Switch 2 titles

Switch 2 titles size their heap from the total memory and stop at the
first unimplemented command, so they only booted with the 12 GiB layout
and EDEN_NX2_AUTO_STUB set by hand. Detect them from main.npdm before the
kernel starts and apply the layout as a per-game value (the configured
layout comes back once the game is closed), and auto-stub unknown
commands from Switch 2 processes.
