[v3] do not activate debug mode by default

[mathieucarbou]

#define UPDATE_DEBUG 1 => should be removed from the header file and not set to 1 by default. The naming could easily conflict with some other headers

#define ELEGANTOTA_DEBUG 1 => should not be set to ` by default.

I have changed to:

// #define ELEGANTOTA_DEBUG 1
// #define UPDATE_DEBUG 1

#ifdef ELEGANTOTA_DEBUG // instead of #if ELEGANTOTA_DEBUG

So that I can use in platformio:

[env:debug]
build_type = debug
build_flags = ${env.build_flags}
  -O0
  -ggdb -ggdb3 -g3
  -D DEBUG
  -D ENABLE_DEBUG
  -D ELEGANTOTA_DEBUG
  -D CORE_DEBUG_LEVEL=3

Instead I've wrapped them with #ifndef to set default to 0 - c08acad

UPDATE_DEBUG is from Update.h inside ESP core - This provides more useful data for debugging OTA procedure. Anyways, disabled them by default.
