Nyx: emuMMC Manage window, Tools UI, and misc updates

- Add gui_emu_tools: emuMMC Manage window with correct positioning (LV_PROTECT_PARENT + re-parent to win)
- Tools: single SD button (tap = SD partition manager, 3s hold = eMMC)
- Remove emuSD from Nyx UI (tabs, UMS, partition manager); keep bootloader emusd
- Shorten Create emuMMC description text by one character
- Storage/build/config and dependency updates
