Add browser support matrix to other pages

[rhauck]

it's been added to Shapes in #149. Logging this separately to be added to blend modes, clipping/masking, svg, regions, and filters.

Not sure what to do when there are multiple properties (blend-modes, clip/mask). We could do one composite table, one table for each property, or maybe add a row for each property. I did a mockup of the last one, but not sure if it works so well. I'm not sure if there's space on the side for the properties there either.

Hmm. I took another look at how we're currently showing this info... both on the shapes page where we have a this support matrix and on the blend modes page. Taking another look, I wonder if we need to keep the text there with a longhand description of the support (we left it in for shapes, but it's underneath the table).

If we want to leave the text in, it would separate the tables a little, but still looks like too much:

Also, on the shapes page, we don't explicitly list the shape-outside property name.... maybe we should?
