Dart object API (#6682)

Browse Source 
* dart test scripts - generate with `--gen-object-api`

* Dart object API, pack and unpack methods (WIP)

* Dart flatc - extract Builder code to separate functions to reuse it in Pack()

* Dart flatc - use builder field-building implementation in pack()

* Dart flatc - add pack() as an intance method of the "T" class

* Dart object API - make inner fields unpacked as well

* Dart object API - use pack() when collecting field offsets

* Dart object API - use packOnce() for fields that are structs or vectors of structs

* Dart object API - remove obsolete union support TODO

* Dart object API - minor review changes, test and fixes

* Dart object API - revert packOnce() - not supported by other object API implementations

* Dart object API - update docs

* update dart generated code in tests/ to fix CI failure on ./scripts/check-generated-code.sh

* Dart flatc - fix compilation for old MSVC and c++0x
