Updates for riscv support * Target components pull in xtensa component directly * Use CPU HAL where applicable * Remove unnecessary xtensa headers * Compilation changes necessary to support non-xtensa gcc types (ie int32_t/uint32_t is no longer signed/unsigned int).

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.
