headers/deps: net: Optimize <net/dst_api.h> dependencies, remove various headers

          --------------------------------------------------------------------
          | Combined, preprocessed C code size of header, without line markers,
          | with comments stripped:
          -------------------------
  before: | #include <net/dst_api.h>                | LOC: 18,092 | headers:  367
   after: | #include <net/dst_api.h>                | LOC: 16,492 | headers:  317

Fix up dangling dependencies.
