URL: https://github.com/apache/incubator-nuttx/pull/5671


   ## Summary
   This PR intends to add support for the Free-running Timer wrapper component.
   
   ## Impact
   Extended OS support for `esp32s3-devkit` platform.
   
   ## Testing
   Tested using `esp32s3-devkit:timer` as a baseline configuration and creating a simple test application:
   
   ```c
   int main(int argc, FAR char *argv[]) {
     struct esp32s3_freerun_s freerun;
     struct timespec ts = { 0 };
     struct timespec sleep_time = { .tv_sec = 0, .tv_nsec = 300 * NSEC_PER_MSEC };
     int i = 0;
   
     esp32s3_freerun_initialize(&freerun, 1, 1);
   
     while (i++ < 10) {
         esp32s3_freerun_counter(&freerun, &ts);
   
         nanosleep(&sleep_time, NULL);
     }
   
     esp32s3_freerun_uninitialize(&freerun);
   
     return 0;
   }
   ```
   Output:
   ```
