Add JCB variables for horizontal localization radius and halo size used in GETKF

[SamuelDegelia-NOAA]

Description

When setting up the JEDI-based EnKF retros in rrfs-workflow, it was found that the horizontal localization settings in our JEDI YAMLs did not match those used in GSI-based RRFSv1. To address this, this small PR adds JCB variables that allow the horizontal localization radius and halo size to be configured explicitly. Separate variables are defined for conventional and dbz observations to be consistent with the existing RRFSv1 configuration.

The default values in the YAMLs are unchanged so that the current ctest results remain identical. At this stage, the updated localization values will be applied only through the JCB configuration files used by in rrfs-workflow.

For reference, the following GSI values are currently used and will be adopted for the upcoming retros:

CORRLENGTH = 300
CORRLENGTH_radardbz = 18
LNSIGCUTOFF = 0.5
LNSIGCUTOFF_radardbz = 0.5

Note that the vertical localization lengthscale is already configurable as a JCB variable and matches what is used in GSI.

The error for rrfs_fv3jedi_2024052700_3denvar_refl seems to be due to instability on Hera:

srun: job 21776016 queued and waiting for resources
srun: job 21776016 has been allocated resources
srun: error: h4c08: tasks 49-55: Bus error

I think this PR is okay to move ahead since the failure is not related to this PR.
