Internal timing: Add notice that the -I and internal_timing option are no longer needed.

Add notice messages during execution that the -I command line option and
the astersik.conf internal_timing option are no longer needed.  The
internal timing functionality is now always enabled if there is a timing
module loaded.

NOTE: Since the command line options and the asterisk.conf config file are
processed before the logging system is initialized, the messages are
output to stderr.

Change requested as a result of asterisk-dev list comments about the
commit for ASTERISK-22846 that removed the -I and internal_timing options.
