Abdessamad Derraz 801a0150e6 feat: run the handheld launchers in the tui
The PortMaster port now starts install.py --tui on the console (or in
foot or xterm under a compositor), with gptokeyb in kill mode on the
installer's path, retrobios.gptk, TERM=linux and a Terminus font, and
puts the console, font and mapper back on exit. pugwash screens stay as
the fallback where no terminal can show, and start in no-check mode so
PortMaster's A/B fix applies. Without a network, every launcher installs
from a pack found on the card or names the pack and the folder.

Adds launchers for Batocera and Knulli (Ports, evmapy .keys), muOS
(.muxapp in muxterm with gptokeyb2) and the Tools menu of ArkOS,
dArkOS, ROCKNIX, JELOS and AmberELEC, built by build_port.py with the
pinned installer and tested on a simulated device.

Notes

RetroBIOS runs the RetroBIOS installer (install.py, from github.com/Abdess/retrobios) on the device, in its full-screen interface. The installer finds the BIOS folder of the system, checks every file its emulators read against its hash, and installs the missing ones.

With a network connection the files are downloaded. Without one, copy the BIOS pack of your system (a _BIOS_Pack.zip file from the releases page) into ports/retrobios on the card, and RetroBIOS installs from it.

Python 3.8 or newer: the system's, or PortMaster's python_3.11 runtime on aarch64, downloaded on first use.

Under a desktop session with neither foot nor xterm, RetroBIOS opens PortMaster's own screens instead of the full-screen interface.
