[Enhancement] aws_codepipeline: support for Compute action

[tabito-hara]

Description

• Add several arguments to the action block to support the Compute action:

  • commands

  • output_variables

  • output_artifacts_for_compute_action

    • This argument does not directly correspond to the AWS API objects.
    • In the AWS API, OutputArtifacts is an object with two attributes. However, in Terraform, the existing output_artifacts is implemented as a list of artifact names.
    • The Compute action uses the files attribute in OutputArtifacts, which cannot be represented using the current output_artifacts.
    • To avoid affecting existing configurations, a new argument, output_artifacts_for_compute_action, has been introduced. Its schema matches that of the OutputArtifacts object in the AWS API.
    • When the action is Compute, output_artifacts_for_compute_action is used and output_artifacts is ignored.
    • For all other actions, the reverse applies.

• This PR is based on f/aws_codepipeline add 'commands' attribute to support 'Compute' action category #41034, rebased onto the latest main branch, and adds the output_variables and output_artifacts_for_compute_action arguments.
