* RPC: Update protobuf sources * RPC: Add Virtual Display * Unify log tags * RPC: Virtual Display placeholder * Rpc: clear frame buffer callback before confirm. * Firmware: full assert for hal, move fatfs initialization to furi hal. * FuriHal: VCP optimizations, thread safe console. Rpc: adjust buffer sizes. Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
