[23153] Generate code for interfaces and support @nested

[MiguelCompany]

Description

This PR adds C++ code generation for IDL interfaces (a.k.a RPC).

• The generated client interface provides an asynchronous API based on std::future.
• The generated server interface allows for aggregating the operation implementation (thus decoupling the DDS logic from the operation logic)
• Includes support for custom extension @feed.

This PR depends on the following ones and must be merged after them:

• [23153] Improvements on RPC entities Fast-DDS#5801
• [22768] Set index on exception members IDL-Parser#172
• [23153] Improvements for interface and @nested IDL-Parser#176
• [23153] Add test files for RPC related entities dds-types-test#43

The generated code for the following IDL is not compiling.

exception MyEx
{
    long id;
    string message;
};

interface MyIf
{
    exception MyEx2
    {
        long id;
        string message;
    };

    struct MySt
    {
        char array[30];
    };

    void test1(in short s, out string m) raises (MyEx);

    string test2(inout char s, inout string m) raises (MyEx2);

    @feed
     MySt test3(in long id) raises (MyEx);
};
