Add missing headers

Most of these were found by breaking every redfish class handler into
its own compile unit:

When that's done, these missing headers become compile errors. We
should just fix them.

In addition, this allows us to enable automatic header checking in
clang-tidy using misc-header-cleaner. Because the compiler can now
"see" all the defines, it no longer tries to remove headers that it
thinks are unused.

Tested: Code compiles.
