ericwyuan 398018b51e Rebuild the face against the design kit; make fields configurable ...

Vendor the watchface-kit into design/ and derive everything from it instead
of from hand-transcribed constants.

Geometry, from design/rebuild.py and the ink boxes of the traced SVG paths:
  - ring ticks are annular sectors (fillPolygon), not radial lines
  - top arc is 21 ticks at 6.5+4k, not 22 at 2+4k
  - exact radii, tick widths, anchor dots, band and colon rectangles
  - element positions taken from measured ink bounding boxes

Colour, generated by tools/gen_themes.py straight out of the comps:
  - per-tick colour tables (21+21) replace 9/7 interpolated stops
  - 11-stop vertical gradients on the time digits, drawn with clip banding
  - per-element accent / value colours and per-theme unlit tick colour

Data: the design's sunrise and hi/lo fields turn out to be available after
all -- Weather.getSunrise and getDailyForecast both exist in SDK 9.1.0 --
so both are restored, and heart rate is added alongside them.

Bugs found on the way:
  - Gregorian FORMAT_MEDIUM returns day_of_week/month as strings, so the
    date band crashed on every update (caught in the simulator)
  - Stats.battery is already 0-100, multiplying by 100 gave "4000%"
  - moveBarLevel is an integer level 0..5, not a 0..1 ratio, so the move
    bar arc was all-or-nothing

Also: all four field slots are configurable with labels that follow the
selection, temperature unit is a setting, on-face wording moved into
resources with a Simplified Chinese variant, and 24h/distance/temperature
now follow the watch. Fonts are chosen by measured cap height rather than
by ascent.

Verified in the Connect IQ simulator on fenix847mm and by compiling all
17 target devices.
