Proposal

Additional margin and padding classes that allow to extract column space from container to left or right side.

Demo: https://codepen.io/ArtZ91/pen/wvPgMQX

1. Add --container-max-width CSS variables.
2. Add classes like ms-n-auto and me-n-auto for new margin values.
3. Add classes like ps-auto and pe-auto for new padding values.

Motivation and context

Some designers like to draw blocks that start from the viewport side and ends inside container column.
