[FL-1196] Targets: add F6 (#427)

* 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

+  * @author  MCD Application Team
+  * @brief   CMSIS Cortex Device Peripheral Access Layer System Source File
+  *
+  *   This file provides two functions and one global variable to be called from
+  *   user application:
+  *      - SystemInit(): This function is called at startup just after reset and
+  *                      before branch to main program. This call is made inside
+  *                      the "startup_stm32wbxx.s" file.
+  *
+  *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+  *                                  by the user application to setup the SysTick
+  *                                  timer or configure other parameters.
+  *
+  *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+  *                                 be called whenever the core clock is changed
+  *                                 during program execution.
+  *
+  *   After each device reset the MSI (4 MHz) is used as system clock source.
+  *   Then SystemInit() function is called, in "startup_stm32wbxx.s" file, to
+  *   configure the system clock before to branch to main program.
+  *
+  *   This file configures the system clock as follows:
