Move code specific to pg_dependencies to new fileHEADmaster

This new file is named pg_dependencies.c and includes all the code
directly related to the data type pg_dependencies, extracted from the
extended statistics code.

Some patches are under discussion to change its input and output
functions, and this separation makes the follow-up changes cleaner by
separating the logic related to the data type and the functional
dependencies statistics core logic in dependencies.c.
