* 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
