Effects factory: Implement xml config loading
For treble, files shared between vendor and system must have a schema.
As .conf did not support such feature, transition to an xml based
configuration file.
This new format has several changes:
- library path are now relative to the standard effect directories
- effect parameters are no longer supported (nobody used them)
Test: Check that the dumpsys is similar than with the legacy formal
