Builder pattern for MediaProjectionConfig

Introduce a builder pattern for
MediaProjectionConfig, allowing more flexibility for the type of
configuration need by the requesting application, in preparation for the
content sharing option in a follow-up CL.

Also adding some documentation fix and moving readding the CTS in
presubmit.
