[C++] Check for case insensitive keywords (#8420)
* chore(idl): Check for case insensitive keywords

Most languages are not affected by this change. In PHP, some names such
as Bool cannot be used because it is a reserved keyword for to the bool
data type. The field `keywords_casing` in the configs enables checking
all characters in lowercase against every keyword. This should be safe
as flatbuffers does not allow non-ASCII characters in its grammar.

* chore: Fix formatting to follow google's coding style for enums

* chore: Extract convert case to lower when CaseInsensitive

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++.
