Show if ASAN build in --show-config (#2650)

This commit extends `--show-config` to show whether the current build is
an ASAN build or not. This is done by moving a detection that was
previously done for the unit tests into base/configuration_private.h.

In addition to being convenient, this allows us to easily exclude
regression tests from ASAN builds.
