Caniuse: Support for CSS grid's subgrid

[alecf]

this is vital for proper CSS grid support, I think not supported by any browsers yet..

Subgrid's been moved to "level 2" of the CSS grid spec, so maybe a new feature CSS grid layout - level 2 could be added.

We will need some way for Can I use to reflect the state of subgrid. Which kind of gets at one of the complexity's of running Can I Use — how best does an overall Yes/No capture the giant pile of details about the answer to the question "does this work yet?".

So far, everything for CSS Grid was written into the Level 1 spec. Which did change a bit. And some of the newest parts are not supported yet, even though Can I Use says they have full support (for example: renaming grid-gap to be gap).

Everything about subgrid is in the Level 2 spec. https://www.w3.org/TR/css-grid-2/ So perhaps the easiest way to handle this is to add a page to Can Use for CSS Grid level 2 (and alias the search terms to subgrid + put "subgrid" on the page someplace).

Subgrid is being currently implemented in Firefox. So it's coming soon ('soon' in browser evolutionary terms... so 2019).

I decided to go for subgrid specifically for now since that's what people are most interested in. In the future may change it to Grid Level 2 if support for the spec's subfeatures doesn't get too complicated.
