Move test_cli_remapping into test_cli

[Aaravanand00]

Description

This PR consolidates the test_cli_remapping package into the test_cli package to reduce the overhead of having too many granular test packages, keeping related CLI tests together.

All source files for the remapping tests have been moved into test_cli/test/ and the build configurations (CMakeLists.txt and package.xml) have been merged accordingly. The old test_cli_remapping package has been entirely removed.

Fixes #279

Is this user-facing behavior change?

No, this is purely an internal structural change to consolidate testing packages.

Did you use Generative AI?

I did use generative AI in some form in making the content of this
pull request.

Additional Information

• Verified that test_cli successfully builds with the newly migrated remapping test (name_maker_rclcpp executable and test_cli_remapping.py launch test).
• Test dependencies (launch_testing_ros, launch_testing_ament_cmake, test_msgs, etc.) have been moved over to test_cli.

Hi @fujitatomoya @skyegalaxy

In this PR, I have resolved issue #279 by moving the test_cli_remapping package into the test_cli package.

1. Moved the source files (name_maker.cpp, name_maker.py, test_cli_remapping.py) into test_cli/test/.
2. Merged the required dependencies and build targets into test_cli's CMakeLists.txt and package.xml.
3. Deleted the old test_cli_remapping package completely to reduce boilerplate and package overhead.

I have tested the build locally and it compiles successfully. The tests are ready let me know if any changes are needed...
