[FL-950] CC1101 Stage1, SPI Refactoring, Drivers layer (#386)
* API HAL SPI: refactoring, split into layers, prepare ST HAL separation. API HAL SubGhz: initialize on start. Drivers: add basic cc1101 driver. Update API usage. Debug: increase max debugger port speed. Remove subghz apps.
* CC1101: chip status handling. ApiHalSpi: increase SubGhz bus speed to 8mhz. F4: backport subghz initialization.
* Api Hal SubGhz: rx path and frequency. CC1101: frequency control.
* SubGhz Application: basic tests
* SubGhz app: tone and packet test. API HAL SUBGHZ: update configs, add missing bits and pieces.
