[color-swatch][color-scale] Option to show coords

[LeaVerou]

<color-swatch> should support an option to list any coords in any color space. Name TBB, let's use coords for now.
Type would be array of objects and the default label would be the coord name.

<color-swatch color="#f8f9fa" coords="L: oklch.l, C: oklch.c, H: oklch.h"></color-swatch>

Rendering could look like this. Ideally should have a container query that lays out horizontally unless there is not enough space.

<color-scale> should support the same attribute and just pass it along to its swatches.

This has now been implemented (thanks @DmitrySharabin)
