[FL-1558] Technical Debt: console, bootloader, targets, stdglue, etc... (#590)

* ApiHal: console abstraction, change uart baud rate to 230400. Bootloader: drop F5. Furi: prevent thread local output to serial console in stdglue.
* ApiHal: take control over system initialization, reorder some subsystems in a hope of fixing USB issues.
* Main: cleanup dead code. ISR: take care of HSECSS by our self. USB: leave clock configuration alone.
* F6 cube: switch RCC to LL.
* Cli: rollback return behavior.
