[Swift] Adds new API to reduce memory copying within swift (#8484)
* Adds new API to reduce memory copying within swift

Adds new storage container _InternalByteBuffer which
will be holding the data that will be created within the swift
lib, however reading data will be redirected to ByteBuffer, which
should be able to handle all types of data that swift provide without
the need to copy the data itself. This is due to holding a reference to
the data.

Replaces assumingMemoryBinding with bindMemory which is safer

Adds function that provides access to a UnsafeBufferPointer for
scalars and NativeStructs within swift

Updates docs

Suppress compilation warnings by replacing var with let

Using overflow operators within swift to improve performance

Adds tests for GRPC message creation from a retained _InternalByteBuffer

FlatBuffers is a cross platform serialization library architected for maximum memory efficiency. It allows you to directly access serialized data without parsing/unpacking it first, while still having great forwards/backwards compatibility.

Quick Start

  1. Build the compiler for flatbuffers (flatc)

    Use cmake to create the build files for your platform and then perform the compilation (Linux example).

    cmake -G "Unix Makefiles"
    make -j
    
  2. Define your flatbuffer schema (.fbs)

    Write the schema to define the data you want to serialize. See monster.fbs for an example.

  3. Generate code for your language(s)

    Use the flatc compiler to take your schema and generate language-specific code:

    ./flatc --cpp --rust monster.fbs
    

    Which generates monster_generated.h and monster_generated.rs files.

  4. Serialize data

    Use the generated code, as well as the FlatBufferBuilder to construct your serialized buffer. (C++ example)

  5. Transmit/store/save Buffer

    Use your serialized buffer however you want. Send it to someone, save it for later, etc...

  6. Read the data

    Use the generated accessors to read the data from the serialized buffer.

    It doesn't need to be the same language/schema version, FlatBuffers ensures the data is readable across languages and schema versions. See the Rust example reading the data written by C++.
