dev-embedded/arduino-ide: add 2.3.7, definitely different from arduino

- This is definitely a new package, different from package in ::gentoo
  `dev-embedded/arduino::gentoo`
- Arduino IDE 2.x is a completely new application based on
  Eclipse Theia, and can coexist with the classic Arduino IDE 1.x.
