Improve how CSS modules handle map flattening (#2663)

The goal of this PR is to make handling of maps within the context of the `core/css` module more consistent. This also applies to modules that expand the CSS module, such as `core/theme`. To do this, there are three new utilities added:

- `args-to-map` - Converts various combinations of the prop and value arguments into a single prefixed and flattened map.
- `flatten-map` - A utility function to flatten a multi-level map by prefixing each level with the previous map's key. The only map that isn't flattened and stored directly are maps with the `"config"` key.
- `prefix-map` - Prefix all map keys with a provided string value

**Additional changes**
- `core/theme` - Now takes the `theme` argument first before component and other arguments. This is to help make the theme API more intuitive.
- `core/theme` - Added theme check to `theme.class` function
