Mono: Logging improvements 

- The default log level in debug builds is now 'info' instead of 'debug'.
- Add option to specify a different log level with the 'GODOT_MONO_LOG_LEVEL' environment variable.
- The name of log files is now a readable date and time.
- Always print the log file path (previously it was printed only it in verbose mode).

(cherry picked from commit 20e5e2fec7)
