[FL-1666] Bootloader: info screen when we going to DFU. FuriHal: port SPI to LL. Cleanup. (#634)

* FuriHal: port spi to ll. Bootloader: add spi and display.
* Makefile: rollback disabled freertos introspection
* FuriHal: spi lock asserts. F6: minor cleanup port sdcard shenanigans to furi_hal_gpio.
* SdCard: port missing bits to furi-hal-gpio
* FuriHal: fix broken RX in SPI, update SPI API usage. RFAL: more asserts in SPI platform code.
* GUI: clear canvas on start. FuriHal: no pullup on radio spi bus.
* FuriHal: use check instead of assert in spi lock routines
* FuriHal: remove timeouts
* SdHal: add guard time to SDCARD CS PIN control.
* FuriHal: proper name for SPI device reconfigure routine. SdHal: one more enterprise delay and better documentation.
* Bootloader: update DFU text and add image.
* FuriHal: drop unused ST HAL modules.
* SdHal: fixed swapped hal_gpio_init_ex arguments
* SpiHal: fixed swapped hal_gpio_init_ex arguments
* IrdaHal: use hal_gpio_init instead of hal_gpio_init_ex
* RfidHal: fixed swapped hal_gpio_init_ex arguments
