[CI environment] Extend and optimize resource removal of nested deployments with higher scope than the parent

[eriqua]

Description

Prerequisite for PR #2136 and #2019.
In the new dependencies approach for compute images, a deployment at subscription scope (roleAssignment) is nested in a deployment at resource group scope (rg dependencies). The current removal logic does not cover this scenario and the nested deployment is not fetched when having a higher scope than the parent. Hence the roleAssignment is not removed, and a subsequent validation of the module fails.

• Improving fetching of deployments and resources to delete to support the above scenario.
• Adding roleAssignment removal priority
