feat(vector): Add Shortbread styles and data. BM-1186 (#1037)

### Motivation

We are now generating vector tiles with [shortbread] schema. In order to
support the new schema, we will provide version 2 styles for the new
vector tiles data with new schema mapping in the style json.

Following styles will be added into basemaps:

- [topographic-v2]
- [topolite-v2]
- [labels-v2]

Following styles will be removed from basemaps:

- basic
- positron

### Modifications

- Add a new `topographic-v2.json` tileset config that points to the
shortbread vector tiles data.
- Add new `v2` style configs that mapping the shortbread schema.
- Remove old [openmaptiles] `basic` and `positron` styles that we no
longer maintain.

### Verification

- [topographic-v2]
- [topolite-v2]
- [labels-v2]
