[worksofliam]

Changes

Enables local actions to compile sources from source members. This enables the ability to use CRTDSPF, CRTPF, CRTLF, etc, on local workspace sources.

How to test this PR

Examples:

1. Create a valid display file
2. Create an action in actions.json for CRTDSPF
3. Use the Action runner to use the newly action
4. Put an intential error in the display file
5. Run the action again and expect problems to appear

Also, run the test cases for Actions.
