[C++] #6501 - Problem when mapping a native type multiple times (#6514)

Browse Source 
* [C++] #6501 - Problem when mapping a native type multiple times
- idl.h:
added "native_type_pack_name"
- flatbuffers.h:
added CreateVectorOfNativeStructs variants which receive a pointer to the serialization function
- idl_gen_cpp.cpp:
adapted code generation in case "native_type_pack_name" attribute is present
- extended tests & docs; improved surrounding native_type docs a little

* integrated review feedback

However, it can be useful to instead use a user-defined C++ type since it
can provide more functionality, eg.
struct vector2 {
float x = 0, y = 0;
vector2 operator+(vector2 rhs) const { ... }
vector2 operator-(vector2 rhs) const { ... }

However, because the `native_type` is unknown to flatbuffers, the user must
provide the following functions to aide in the serialization process:
namespace flatbuffers {

Finally, the following top-level attribute
- `native_type_pack_name("name")` (on a struct when `native_type` is
specified, too): when you want to use the same `native_type` multiple times
(e. g. with different precision) you must make the names of the Pack/UnPack
functions unique, otherwise you will run into compile errors. This attribute
appends a name to the expected Pack/UnPack functions. So when you
specify `native_type_pack_name("Vec2")` in the above example you now need to
implement these serialization functions instead:
- `native_include`: "path" (at file level): Because the `native_type` attribute

Finally, the following top-level attributes:
- `native_include("path")` (at file level): Because the `native_type` attribute
can be used to introduce types that are unknown to flatbuffers, it may be
necessary to include "external" header files in the generated code. This
attribute can be used to directly add an #include directive to the top of
