PeriMan: Improve log messages

[lucasssvaz]

Description of Change

This PR aims to improve the Peripheral Manager log messages to help debugging processes.

@SuGlider Please check if you want any other log messages for the PeriMan.

Further investigation shows that the CPU hangs waiting for an interrupt. The following sketch with debug level set to verbose produces this misbehavior (tested on ESP32-S3-DevKitC):

void setup() {
  Serial.begin(115200);
  while(!Serial) { delay(10); }

  pinMode(SOC_RX0, OUTPUT);
  pinMode(SOC_TX0, INPUT);

  delay(100);
  Serial.println("test: This should not be printed");
  Serial.flush();

  Serial.setPins(SOC_RX0, SOC_TX0);
  delay(100);
  Serial.println("test: This should be printed");
  Serial.flush();
}

void loop() {
#ifdef RGB_BUILTIN
  neopixelWrite(RGB_BUILTIN,4,0,0); // Red
  delay(1000);
  neopixelWrite(RGB_BUILTIN,0,4,0); // Green
  delay(1000);
  neopixelWrite(RGB_BUILTIN,0,0,4); // Blue
  delay(1000);
  neopixelWrite(RGB_BUILTIN,0,0,0); // Off / black
  delay(1000);
#endif
}

The backtrace of when the processor hangs:

#0  0x4037972e in esp_cpu_wait_for_intr () at /home/runner/work/esp32-arduino-lib-builder/esp32-arduino-lib-builder/esp-idf/components/esp_hw_support/cpu.c:121

@SuGlider Might this be related to the issue you are seeing in #8809 ?

[me-no-dev]

maybe the fact that you are modifying the default UART pins, without deinitializing the UART first, is the problem :)

[SuGlider]

these issues that Lucas has reported are solved with #8820 - including hanging while using logging.

The issue with verbose was related to dead lock. Solved with #8820
Teste this sketch with and without logging - C6 and S3. All fine now.
