Seandroid: Add policies to enable all QDCM functionalities

Address all SELinux denial messages related to QDCM tool
functionality and the color service SDK application.

Add policies to allow:
1- /persist/ read & write for display confid
2- /data/misc/display/ read & write
3- Allow access to colorservice for display sdk from android app.
4- Enable pp-daemon functionalities for the non user-debug and
eng builds, since OEMs actively use QDCM tool, and they require
full functionality.
