Update to MYNN-EDMF

[joeolson42]

Description

Code universalization needed (CCPP, WRF, and MPAS). New features, tuning, and code clean-ups. The primary goal is to overhaul/retune the subgrid clouds after important conservation changes were made. An overview of the required work:

• remove the first-order for of Chaboureau-Bechtold (CB) and replace with the q'2 version of CB
• Added 3d variable "sm3d" - stability function for momentum, and TKE budget arrays
• fixed some old crash cases (improved numerical stability)
• conservation work - remove negative qv events
• A bug fix for the interpolation of the mass-flux clouds from interface levels to mid-levels which cause excessive LWP in shallow-cumulus fields
• Fixes for the smoke/chemical mixing in MYNN-EDMF
• Change the default mixing length option to 1 and to run at level 2.6
• General clean up of code and updates to many comments (also responsible for many lines of code changes).

Solution
