packages_list: allow filtering by pkg name

Introduces a new data source config, since this source didn't have one
before. If the new filter is non-empty, then only matching entries will
be emitted into the trace. If the filter is empty, emit everything as
before.

qt-dev cherry-pick addendum: using the c++ generated classes instead of
the protozero decoder for parsing the config. Q branch predates the
"lazy" config fields.

Tested: manually on crosshatch-userdebug
