ENH: Allow projects to disable per-rule echo lines

This creates global property RULE_MESSAGES which can be set to disbale
per-rule progress and action reporting.  On Windows, these reports may
cause a noticable delay due to the cost of starting extra processes.
This feature will allow scripted builds to avoid the cost since they do
not need detailed information anyway.  This replaces the RULE_PROGRESS
property created earlier as it is more complete.  See issue #8726.
