HEAP memory in physics schemes

[dustinswales]

Description

Some schemes rely on the dynamic use of HEAP memory (e.g module memory). This is problematic for host model applications that wish to run multiple instances of the ccpp-physics within the same executable, where we run into the issue of multiple tasks trying to read/write to the same memory.

Solution

Remove dynamic HEAP references from parameterizations and replace with Interstitials. This way each ccpp instance is self contained and "stateless" (no dynamic shared memory). This is straightforward for some schemes (i.e. Thompson MP), while quite invasive to others (i.e. ozone physics and RRTMGP).
