Make showTileBoundaries prefer a vector source

[jleedev]

Fixes #833

[jleedev]

I don't know why the render test doesn't trip. Manual test:

The render test doesn't trip because it's a raster maxzoom of 1 and a vector maxzoom of 14.

This adds a test with raster maxzoom of 17. Old behavior was to show tile boundaries for the raster source, and 0 kB. New behavior is to show tile boundaries and byte sizes for the vector tiles.

Any change for a unit test?

[jleedev]

Could factor out the logic to an exported function in either painter.ts or draw_debug.ts, then invoke it with various Maps and assert that it returns the desired SourceCache.

The logic is currently inside a single 155-line function named render.

Exporting the show tile boundaries to a different method/file and testing it would be great, thanks!
