User/bgr/ideal hurricane

Add idealized_hurricane test case to ocean_only.

• This P/R has been confirmed to not change answers in ocean_only and ice_ocean_SIS2 experiments if taken in conjunction with forthcoming MOM6 P/R (user/bgr/ideal_hurricane_config).
• Key feature is addition of new test case idealized_hurricane and associated input files.
• The SCM_idealized_hurricane routine was completely changed so it can be used to map both single location and 3d wind from the parametric (Holland, 1980) wind profile. These changes have been updated in the SCM_idealized_hurricane ocean_only test case input files.
• The SCM_idealized_hurricane routine previously also contained a TS initialization that is removed in user/bgr/ideal_hurricane_config MOM6 P/R because of redundancy with the CVMix_tests TS initialization (which should ultimately be relocated into the main state initialization). Therefore CVMix_SCM_tests folder in ocean_only has been updated to use the CVMix_tests TS instead of the idealized hurricane TS initialization.
• The CVMix_SCM_tests folder was renamed from CVmix_SCM_tests folder to agree with convention of using "CVMix". This rename is unrelated to the rest of the P/R, so could be reverted if it is more trouble than its worth.
• All MOM_parameter_doc.___ files have been updated according to the new options.

Thanks for this PR, @breichl. However changing the directory name from CVmix_SCM_tests folder to CVMix_SCM_tests is disrupting our testing of this and the other changes. If there is any way that you could revert that specific change so that we can separately accept the code changes, that would be helpful for the testing process.
