Add auto-dispatch specification to Intel packages (#11697)

Browse Source 
This PR adds the ability to specify the auto-dispatch targets that can
be used by the Intel compilers. The `-ax` flag will be written to the
respective compiler configuration files. This ability is very handy when
wanting to build optimized builds for various architectures. This PR
does not set any optimization flags, however.
