Configure aerosol-phase-specific Species for solver

[boulderdaze]

When a species like CO2 exists in multiple modes/sections, the current MICM API cannot handle which instance it needs to react.

This PR:

• Adds the ability to set an aerosol-phase-specific scope for species during solver construction.
  For example, CO2 can exist in gas phase, or in a mode/section-phase-specific form.

  CO2
  ACCUMULATION.ORGANIC.CO2
  AITKEN.AQUEOUS.CO2

• Closes Non-gas-phase Species not found when constructing ProcessSet #888

Pull request overview

This PR adds aerosol-phase-specific scoping functionality to the chemical reaction builder, allowing species names to be prefixed with aerosol mode and phase identifiers. This enables the solver to distinguish between the same chemical species in different aerosol phases and modes.

Key Changes:

• Introduced SetAerosolScope method to enable automatic scoping of reactant and product species names
• Modified SetReactants and SetProducts methods to apply scoping when enabled
• Added comprehensive test coverage for the new scoping functionality

I don't understand why we need the scope. The issue mentioned in #888 was that a species in a phase couldn't be found and said nothing about a scope. Wouldn't this be fixed only by updating the species name?

species.name_ = phase.name_ + "." + species.name_;
