Don't assume 'grep' supports GREP_OPTIONS.

The GREP_OPTIONS environment variable is planned to be marked
obsolescent in GNU grep, due to problems in its use, so stop
relying on it.
* progmodes/grep.el (grep-highlight-matches): Document this.
(grep-process-setup): Do not set GREP_OPTIONS.
(grep-compute-defaults): Use an explicit --color option if supported.
