SD-Card: proper HAL (#3058)
* Storage: remove unused error from SDInfo
* FatFS: remove sd_spi_io
* HAL: sd card api
* Update: use sd hal
* FatFS: use sd hal
* Storage: use sd hal
* API: sd hal
* Fix TODO workflow
* SD Hal: Fix source buffer overflow
* fix for fix!
* HAL: cleanup sd detection api
* HAL: FURI_HAL_SD_SPI_DEBUG flag
* HAL: FuriHalSdStatus -> FuriStatus
* API: downgrade
* Change define logic
* HAL: presence
