Parse dumpsys settings as per-record results

The `dumpsys settings` parser matched a single regex per line, which
truncated every value that spans more than one line and, when
`defaultSystemSet:` did not fall on the first line, left the trailing
`default:` metadata inside the value. It also keyed results by setting
name within a namespace, so a name recorded twice kept only the last row
and a row without a `pkg:` field was dropped entirely.

Replace it with a line loop that accumulates one record at a time and
splits the `key:value` fields once the whole record has been read.
Results become a list of records carrying the fields dumpsys prints:
namespace, user, _id, name, value, pkg, default and defaultSystemSet,
plus the per-setting change history. History timestamps are printed
without a year, so they are resolved against the "ending at:" time of
the section and serialized into the timeline. This shows which package
changed a security-relevant setting, and when.

The androidqf settings module shares this artifact, so it now emits the
same record shape.
