PR to remove PHP PEAR modules

[Christopher Chavez]

I have opened a pull request to remove the 500+ ports for PHP PEAR
modules and their portgroup:
https://github.com/macports/macports-ports/pull/4192

This was suggested by Ryan in https://trac.macports.org/ticket/56424 .
Perry agreed with this idea.

One question I have is whether ports PEAR modules from pear.phpunit.de
(such as php-timer) should be deleted as well.

It was suggested that I bring attention to this on the mailing list to
get more feedback from members.
