Remove warnings, errors during host tests in CI (#8358)

* Remove warnings, errors during host tests in CI

Debug strings often included format parameters which did not exactly match
the passed in format parameters, resulting in warnings in the host test build
process like
````
/home/runner/work/Arduino/Arduino/libraries/ESP8266WiFi/src/ESP8266WiFiAP.cpp:107:20: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 3 has type ‘size_t’ {aka ‘long unsigned int’} [-Wformat=]
  107 |         DEBUG_WIFI("[AP] SSID length %u, too long or missing!\n", ssid_len);
      |                                                                   ~~~~~~~~
      |                                                                   |
      |                                                                   size_t {aka long unsigned int}
````

Fix by applying casting or PRxxx macros as appropriate.

Also, fix one debug message which was trying to use a `String` as a `char *`:
````
