Add Native ROS2 Rust Package Create Capability

[parth-20-07]

Description

Add a native support to generate Rust Package rather than breaking workflow from ros2_rust using:

ros2 pkg create --build_type ament_cargo <library_name>

Fixes #1104

Is this user-facing behavior change?

Now users can natively generate rust packages for ros2 using ros2 pkg create rather than using ros2_rust api.

Did you use Generative AI?

No

Additional Information

• Generates package with file structure:

.
├── Cargo.lock
├── Cargo.toml
├── package.xml
└── src
    └── main.rs

1 directory, 4 files

• Initial format/structure provided by @ibrahimsel has been used to develop this.
• Optional node_name parameter can be passed to name the node in main.rs but in absence of the parameter, the <library_name>_node is used in place to generate node_name.
