[release] Make release scripts work without gnumbd

[release] Make release scripts work without gnumbd

This splits branch ref creation and landing. The ref now directly uses
heads (without pending) and for landing we use depot_tools.

For simplicity, the check for existing tags is removed, as it now
is very unlikely to happen again without gnumbd.
