Use GIT tracked branches for arc land targets when reasonable

Browse source 
Summary:
See T5690.
-arc land now respects tracked branch when choosing 'onto'; '--onto' option remains as an override.
-arc land now respects tracked branch when choosing a remote; the remote is taken from 'onto's upstream unless the '--remote' option is present; when 'onto' branch has no upstream the '--remote' option must be provided as before.

Since 'arc feature' branches are (already) created as tracking branches, 'arc.land.onto.default' if present, is only used as the default when a non-tracking branch created by some other means is landed with out explicit '--onto'.  This may be surprising but is probably the correct go-forward behavior and is inline with the description in T5690.

Test Plan:
-checked having no arc.land.onto.default still assumes 'master'
-checked 'arc.land.onto.default' still overrides 'master'
-checked upstream branch (of feature branch) overrides 'master' and 'arc.land.onto.default'
-checked '--onto' overrides all
-checked origin is default for non-tracking branches
-checked the land onto branch's upstream remote is used instead of 'origin'
-checked '--remote' overrides 'origin' and the tracked upstream
-tested several crazy branch names including 'something/like/this' for both the upstream and tracking branches
-tested on linux and OS X
-rinse and repeat on Windows
