Move Root Actor Class is Loaded.vi to AFPP Shared.lvlib

[niACS]

Describe the bug
Root Actor Class is Loaded.vi is a member of Message Maker.lvlib. It is invoked by another member of Message Maker.lvlib and by Add Actor Interface.lvlib:CreateNewWizard_IncludeItem.vi.

Root Actor Class is Loaded.vi is the ONLY member of Message Maker.lvlib invoked by a member of Add Actor Interface.lvlib. I want to move it to AFPP Shared.lvlib, to simplify library dependencies for Add Actor Interface.lvlib.

Message Maker.lvlib already depends on AFPP Shared.lvlib, so we would not increase dependency complexity for that library.

To Reproduce
Steps to reproduce the behavior:

1. Open a blank project.
2. Add Add Actor Interface.lvlib to the project
3. Note that Message Maker.lvlib appears under Dependencies.

Expected behavior

1. Open a blank project.
2. Add Add Actor Interface.lvlib to the project
3. Message Maker.lvlib should NOT appear under Dependencies.

Additional context
We should strive to eliminate unneeded complexity in the provider tools wherever possible, to facilitate further development.
