ENH: Refactor custom command rule hashing

This simplifies computation of custom command rule hashes to hash
content exactly chosen as the custom commands are generated.
Unfortunately this will change the hashes of existing build trees from
earlier CMake versions, but this is not a big deal.  The change is
necessary so that in the future we can make optional adjustments to
custom command lines at generate time without changing the hashes every
time the option is changed.
