pgsql: Avoid including vacuum.h in tableam.h and heapam.h.

Avoid including vacuum.h in tableam.h and heapam.h.

Commit 2252fcd427 modified some function prototypes in tableam.h
and heapam.h to take a VacuumParams argument instead of a pointer,
which required including vacuum.h in those headers. vacuum.h has a
reasonably large dependency tree, and headers like tableam.h are
widely included, so this is not ideal. To fix, change the
functions in question to accept a "const VacuumParams *" argument
instead. That allows us to use a forward declaration for
VacuumParams and avoid including vacuum.h. Since vacuum_rel()
needs to scribble on the params argument, we still pass it by value
to that function so that the original struct is not modified.
