Implement name and sha component context interpolation

What does this MR do and why?

Implement name and sha component context interpolation

This is the second step of adding component context to the CI interpolation. In the first step, we've prepared the codebase by refactoring YAML context passing. In this step, we are adding component.name and component.sha to the interpolation. In the next step, we'll add component.version.

The documentation will be added in the final step.

This change is behind the feature flag ci_component_context_interpolation.
