x11/iaito: New port: Official QT frontend of radare2

iaito is the official graphical interface for radare2, a libre reverse
engineering framework.

• Requires radare2 and Qt-5/6.
• Iaito was the original name of this GUI before being forked as Cutter.
• Use r2 plugins (f.ex: no need for r2ghidra-iaito plugin if r2ghidra is installed).
• Focus on simplicity, parity with commands, keybindings and r2-style workflows.
• Aims to cover other radare2 features, not just a disassembler: forensics, networking, bindiffing, solvers, ...
