Add TChem interface for aerosols

[jcurtis2]

• Create aero_data from TChem using getters
  • Get number of aerosol species to allocate aero_data sizes
  • Get species name for each species
  • Get density for each species
  • Get molecular weight for each species
  • Get kappa for each species
• Set the number concentrations from 1:n_part, and 0 for n_part+1 to maximum
• Set the particle species masses in the state vector
• Reconstruct the particle masses from TChem state vector.
• Build process supports CPU and GPU

Testing

• Test CPU code against TChem result
• Test GPU code against TChem result
• Fix tchem tests
