* nox/enable-silent-rules/OTP-10726:
  Implement ./otp_build configure --enable-silent-rules

With silent rules, the output of make is less verbose and compilation
warnings are easier to spot. Silent rules are disabled by default and
can be disabled or enabled at will by make V=0 and make V=1.

Changed the displayed variables to be printed with ~tp to show default
all lists and utf-8 binaries as unicode strings.

If the user want to see the content without unicode strings he can click
on them to see the content as integers, if not it only contains latin1
because ~p converts that.

There is currently no way to display it as lists with indentation,
so I choose to keep it as it was.

wxWidgets contains more code format options and if they
are not set it looks really bad.
