This removes much of the support debugging stuff from evt1. Still to

- Figure out if we need to keep the USB buffering
- Remove extra decoupling caps

Add a footprint from KiCad for the power regulator we'll use.
It refers to a 3D file that doesn't exist, so we'll need to find that
first.

releases: remove evt1 and evt2, and rename evt3 -> evt1
...
evt1 and evt2 were never produced. They also would never have worked,
because the USB connector was drawn mirrored.
Remove these and replace them with a single `evt1` that was actually
produced.
This reflects the fact that the `evt1` boards actually say "EVT1" on
them.

pcb: add our own copies of 3d models and footprints
...
The Kicad default footprints seem volatile and unreliable. Going
between two machines that both have "Kicad 5.0.0" installed results in
incompatibilities because KiCad has renamed their footprint libraries.
Also, for some reason it's going to Github to get footprints instead of
using local copies.
Copy every model and footprint we use into a local tomu-fpga.pretty.
This lets us ensure we can work offline, and also allows us to modify
footprints, e.g. by adding a "Pin 1" marker.
