refactor(hal): extract assist_debug, debug_probe and trace into esp_hal_debug_assist

Move the following modules from the hal component into a new dedicated
esp_hal_debug_assist component, following the esp_hal_timg pattern:

- assist_debug (hal + target-specific LL headers)
- debug_probe (types + target-specific LL headers)
- riscv_trace (hal + types + source + target-specific LL headers)
- trace_ll (esp32/esp32s2/esp32s3 target-specific LL headers)

Update the following components to depend on esp_hal_debug_assist:
esp_system, riscv, bootloader_support, esp_hw_support, esp_riscv_trace

Remove riscv_trace_hal.c from the hal component.
