esp_hw_support: Removed deprecated CPU util functions

The following files were deleted:
- components/esp_hw_support/include/soc/cpu.h
- components/soc/esp32s3/include/soc/cpu.h

The following functions are deprecated:
- get_sp()

The following functions declared in soc/cpu.h are now moved to esp_cpu.h:
- esp_cpu_configure_region_protection()

The following functions declared in soc/cpu.h are now moved to components/xtensa/include/esp_cpu_utils.h:
- esp_cpu_process_stack_pc()

All files with soc/cpu.h inclusion are updated to include esp_cpu.h instead.
