This commit makes changes to cpu_ll.h, cpu_hal.h, and interrupt_controller_hal.h: - Moved to esp_hw_support in order to be deprecated in the future - HAL/LL API now route their calls to esp_cpu.h functions instead Also updated soc_hal.h as follows: - Removed __SOC_HAL_..._OTHER_CORES() macros as they dependend on cpu_hal.h - Made soc_hal.h and soc_ll.h interfaces always inline, and removed soc_hal.c. This commit also updates the XCHAL_ERRATUM_572 workaround by - Removing it's HAL function and invoking the workaround it directly the bootloader - Added missing workaround for the ESP32-S3
