Update LMeX for use with many-to-one spray capability

[d-montgomery]

This PR includes the changes necessary for the new many-to-one spray capability to work in PeleLMeX (see PelePhysics #633. A few comments:

• The many-to-one spray capability has been tested with the SingleDropEvap test case with the PeleMP and GCM models
• The SingleDropEvap test cases have been updated to work with the many-to-one capability, and includes a test for JP8 where there are 67 liquid species depositing to the HyChem POSF10268 gas-phase species. The results agree well with a detailed 67 species mechanism for POSF10268 as shown in PelePhysics #633.
• Many-to-one with Manifold has been enabled and validated.

To do:

• Point PelePhysics submodule to merged many-to-one commit
