Refactor SubstitutionType for increased flexibility

This removes the SubstitutionType enum and the associated arrays of GN
and Ninja substitution names, replacing them with a more dynamic
collection of data.

This is part of a larger refactoring that will allow for additional
types of Tools (e.g. non-C/C++ langauge compilation) to be added more
simply and cleanly.
