CrayPrgEnv: Change default linking mode based on PE version

Browse Source 
Beginning with the 19.06 release of the Cray Programming Environment, the
default linking mode on XC Cray systems is dynamic instead of static.
This updates the CrayPrgEnv compiler wrappers to detect the PE version
being used and behave accordingly.

* In CMake 3.15.0 and 3.15.1 the :variable:`CMAKE_FIND_PACKAGE_PREFER_CONFIG`
variable caused the :command:`find_package` command to fail on a missing
package even without the ``REQUIRED`` option. This has been fixed.

* ``CrayPrgEnv`` compiler wrapper support has been updated for the 19.06
release of the Cray Programming Environment for which the default linking
