RFC: DP aware breakpoints/media queries for mobile

[jpudysz]

Description

Currently, using breakpoints or media queries on mobile returns values in pixels (not in points, meaning the scale factor is ignored).

This behavior can be convenient in cases where you only use media queries for browsers and don't need breakpoints on mobile.

Based on this discussion: #395
we plan to introduce a setting that allows using points instead of pixels on mobile.

I'm still unsure if this should be enabled by default.

Example configuration:

Stylesheet.create({
    // other configs
    settings: {
        nativeBreakpointsMode: 'points'  // defaults to 'pixels'
    }
})

This will only affect mq and breakpoints, while the web logic will remain unchanged.
