Update ~all flatbuffer rules to static_flatbuffer rules

Don't update things that use unions or circular dependencies.

Used buildozer to make most changes; didn't document the precise steps,
but the approximate steps were:
* Alter the load statements to use the new rule.
* Make all flatbuffer_cc_library rules:
  * No longer specify gen_reflections.
  * Move all includes attributes to use deps (including stripping the
    _includes prefix off of the items in the includes list).
* Rename all flatbuffer_cc_library rules to static_flatbuffer rules.
* Manually fix the spyglass flatbuffer_py_library target that depended
  directly on some outputs of the flatbuffer_cc_library macro.
* Manually undo anything that can't build with the new rules (should
  just be the json_to_flatbuffer target, web_proxy_fbs, and one of the
  flatbuffers used to test the static flatbuffers codegen itself).
* Run the cleanup to get rid of unused load statements.
