NCAR/main ccpp-physics sync

[grantfirl]

Description

This is primarily a ccpp-physics sync from NCAR/main back to the ufs-community/ufs/dev branch. Some changes to UFSATM files were necessary are as follows:

• move some static variables from the CCPP_typedefs/Interstitial DDT to GFS_typedefs/GFS_control DDT. This simplifies the interstitial%reset type-bound procedure and was necessary for the SCM code structure.
• add xr_con and xr_eps namelist variables to allow recent changes to the Xu-Randall cloud fraction algorithms configurable by the host. If these variables are not set in the namelist (which is the default for all current workflows and UFS RTs), these are set using the same logic that was used in radiation_clouds.F
• addition of number_of_diagnostic_buckets variable and array dimension growth for 2 diagnostic variables. By default this is set to 1 and the change is transparent for UFS users but this functionality could be used in the future if multiple bucket-clearing intervals are desired
