Expand ESNZ Rose Stem Tests

[Wolfgang Hayek (tinyendian)]

PR Summary

Sci/Tech Reviewer:
Code Reviewer: Sam Clarke-Green (@t00sa)

This PR expands ESNZ Rose Stem testing for LFRic Apps to cover additional test cases and miniapps, closing #468. It also updates the ESNZ site configuration, LFRic build system, and Rose Stem apps to enable these tests:

Changes in common directories:

• A new ifx.mk include file adds support for the Intel OneAPI Fortran compiler to ngarch miniapp builds
• The NCO ncap2 utility on ESNZ's Cascade HPC requires setting flag -A for appending files explicitly; this should not affect other sites where this flag seems to be optional.

This PR depends on MetOffice/lfric_core#359.

Code Quality Checklist

• I have performed a self-review of my own code
• My code follows the project's style guidelines
• Comments have been included that aid understanding and enhance the readability of the code
• My changes generate no new warnings
• All automated checks in the CI pipeline have completed successfully

Testing

• I have tested this change locally, using the LFRic Apps rose-stem suite
• If any tests fail (rose-stem or CI) the reason is understood and acceptable (e.g. kgo changes)
• I have added tests to cover new functionality as appropriate (e.g. system tests, unit tests, etc.)
• Any new tests have been assigned an appropriate amount of compute resource and have been allocated to an appropriate testing group (i.e. the developer tests are for jobs which use a small amount of compute resource and complete in a matter of minutes)
