Add team property to all modules.

This allows vendors (like google) to specify which team owns the test
module and code.

Team is a commonProperty on modules and points to the designate "team"
module.  The DepsMutator adds the dependency on the "team" module and
"GenerateBuildActions" write the team data to intermediate files.

A new singleton rule, all_teams visits all modules and writes out
the proto containing the team for each module.
If a module doesn't have a team, then it finds the package in the
blueprint file and parent directory blueprint files that have a
default_team and uses that team.

Test: m all_teams
Test: go test ./python ./java ./cc ./rust ./android
Test: added team to HelloWorldHostTest and built the new asciiproto target
Test: added package default_team and checkout output proto.
