Gray out unselected rows in table

[djbarnwal]

In TDD gray out rows which are not included or excluded.

This PR also moves the regular-table styles inside the repo so that they can be managed easily.

I like the direction, but I think the gray is too light. See the "2.53" and "2.3" scores for color contrast:

The numbers are close to invisible under the "low contrast" emulation:

Any way we can achieve the same "disabled" effect, but get the color contrast score a bit higher?

Outside of the contrast issue, code looks good, so I'll approve for you to merge at your discretion.

I switched to using ui-copy-disabled-faint class which we use throughout the codebase. Still seeing that the contrast score is low. Since this is an issue for the whole application, will be good to address it separately.
