Make AppDataPath absolute against the AppWorkPath if it is not (#19815)

* Make AppDataPath absolute against the AppWorkPath if it is not

There are multiple repeated issues whereby a non-absolute provided
APP_DATA_PATH causes strange issues.

This PR simply absolutes the APP_DATA_PATH against the AppWorkPath if
its not so. It also ensures that AppWorkPath is also always absolute.
