* Targets: add F6 * F6: Update linker script for use with internal storage * F6: synchronize with F5, add all changes arriving in V9 board, update cube project. Github workflow: add multi-target build, add F6 to build targets. * CI: fix full assembly * CI: better artifact naming scheme * CI: fix artifacts wildcard * F6: Swap C10 - A15, vibro and sdcard detect pins
