[SRU] Support parallel builds for the ubuntu-cpc project

[Robert C Jennings]

[Impact]

Individual image builds need to be broken out for the ubuntu-cpc project to allow for build parallelization. This feature exists for eoan and disco.

[Test Case]

Build all image targets for all architectures and ensure consistent output compared to existing build output:
* Ensure that manifests are the same before and after this change for the 'all' target
* Build all image targets:
  * Ensure that all expected hooks are run within the context of each target
  * Ensure consistent output between those individual targets and the output prior to the change

[Regression Potential]

This is not without significant risk for the ubuntu-cpc project and requires that rigorous testing be performed to address that risk.
