STYLE: engineFoam: Renamed engineFoam -> XiEngineFoam and sprayEngineFoam -> engineFoam

XiEngineFoam is a premixed/partially-premixed combustion engine solver which
exclusively uses the Xi flamelet combustion model.

engineFoam is a general engine solver for inhomogeneous combustion with or
without spray supporting run-time selection of the chemistry-based combustion
model.
