Michael Paquier 2e35c67f95 injection_point: Add injection_points.stats 
This GUC controls if cumulative statistics are enabled or not in the
module.  Custom statistics require the module to be loaded with
shared_preload_libraries, hence this GUC is made PGC_POSTMASTER.  By
default, the stats are disabled.  001_stats.pl is updated to enable the
statistics, as it is the only area where these are required now.

This will be used by an upcoming change for the injection point test
added by 768a9fd553 where stats should not be used, as the test runs a
point callback in a critical section.  And the module injection_points
will need to be loaded with shared_preload_libraries there.

Per discussion with Álvaro Herrera.
