Ninja: Add internal tool to produce a ninja dyndep file for Fortran

Create an internal `cmake -E cmake_ninja_dyndep` tool to read the "ddi"
files generated by `cmake -E cmake_ninja_depends` from all sources in a
target and generate a ninja dyndep file that tells Ninja about Fortran
module dependencies within the target and on target dependencies.
