Allow passing arbitrary arguments to `colcon build` and `colcon test`

[rotu]

Description

This enhancement will solve a whole class of usability issues by letting users completely customize the build behavior.

Original request:

There's no way I can see to suppress other RMW implementations when building from ros2.repos. In general it may be a good option to be able to ignore packages by name.

Completion Criteria

• User can pass arbitrary colcon arguments
• User can filter out unwanted packages

Implementation Notes / Suggestions

This CI action does not allow injecting additional colcon package selection arguments, which would make the functionality trivial.

This enhancement should be treated as "pass arbitrary arguments to colcon build"

Implementation note: maybe allow for passing colcon arguments list of strings for build/test each.
