Port abstract aerosol interface + BAM implementation from CAM to CAM-SIMA

### What is the feature/what would you like to discuss?

Bring in the abstract aerosol interface code from CAM into CAM-SIMA

This is code to be ported into the host model side. atmos_phys companion issue to follow.

Anything interfacing with physics will have quantities provided via the CCPP framework to the physics

## List of modules to port (current CAM `src/chemistry/aerosol`)
* `aerosol_properties_mod` (provides `abstract :: aerosol_properties` & `aero_name_len`)
* `aerosol_state_mod` (provides `abstract :: aerosol_state` & `ptr2d_t`)
* `aerosol_optics_mod` (provides `abstract :: aerosol_optics` for sw/lw props)

After these abstract types are brought in (hopefully copy-pasted so they do not diverge from CAM) bring in bulk aerosol

## Bulk aerosol modules
* `bulk_aerosol_properties_mod` (provides `bulk_aerosol_properties`)
* `bulk_aerosol_state_mod` (provides `bulk_aerosol_state`)
aerosol state depends on pbuf in CAM (when option is `N` -- need to change to constituents object. I think this means there is no distinction between `A` and `N` anymore... to check)

Wire them up to the CCPP'ized BAM (bulk aerosol model)

Then CCPPize the aerosol optics module specific implementations

## Aerosol optics specifics
* Prep work: `rad_constituents` and `phys_prop` (wip in atmos_phys)
* Port whatever is needed from `aerosol_optics_cam` -- this may or may not be on the host model side or atmos_phys side
* `aer_rad_props` wrapper to call `aerosol_optics_cam` (may not be needed)
* `aerosol_optics_cam_sw` / `aerosol_optics_cam_lw` logic needs to be extracted and put into abstract interface
* ... all this in CAM feeds back to `rrtmgp_set_aer_lw`/`rrtmgp_set_aer_sw` -- which calls `aer_rad_props`

call stack in CAM for rrtmgp <-> aer optics

### Is there anyone in particular you want to be part of this conversation?

@peverwhee @nusbaume

### Will this change (regression test) answers?

I Don't Know

### Will you be implementing this enhancement yourself?

Yes, but I will need some help
