[FL-2435] SD over SPI improvements (#2204)
* get rid of BSP layer
* sector_cache: init in any case
* new sd-spi driver: init
* Delete stm32_adafruit_sd.c.old
* Delete spi_sd_hal.c.old
* Storage: faster api lock primitive
* Threads: priority control
* Flags: correct error code
* Spi: dma mode
* SD-card: use DMA for big blocks of SPI data
* Fix wrong SD_TOKEN_START_DATA_MULTIPLE_BLOCK_WRITE value
* do not memset cache if it is NULL
* remove top-level timeouts
* sd hal: disable debug
* Furi HAL: DMA
* Furi HAL RFID: use furi_hal_dma
* Furi HAL DMA: tests
* Furi HAL DMA: docs
* rollback "Furi HAL RFID: use furi_hal_dma"
* 4 channels taken from DMA manager for core HAL.
* Furi HAL DMA: live fast, die young
* RPC tests: increase message buffer
* SPI HAL: use second DMA instance
* sd hal: new CID getter
* SPI hal: use non-DMA version if kernel is not running
* IR hal: generalize DMA definition
* storage: add CID data to sd info
* RFID hal: generalize DMA definition
* SUBGHZ hal: generalize DMA definition. Core hal moved to DMA2.
* Storage: small optimizations, removal of extra mutex
* Storage: redundant macro
* SD hal: more timeouts
* SPI hal: DMA init
* Target: make furi_hal_spi_dma_init symbol private
* Update F18 api symbols
