ENH: Allow projects to disable per-rule progress

This creates global property RULE_PROGRESS which can be set to disbale
per-rule progress reporting.  On Windows, progress reports may cause a
noticable delay due to the cost of starting an extra process.  This
feature will allow scripted builds to avoid the cost since they do not
need detailed progress anyway.  See issue #8726.
