[RFC]: add dedicated packages for terminal colors and terminal color-detection

This RFC proposes adding packages for terminal colors and terminal color detection.

Potential locations for the package are discussed [here](https://github.com/stdlib-js/stdlib/pull/2254#discussion_r1610842438). Namely adding something along the lines of `@stdlib/cli/colors` and `@stdlib/assert/supports-color` is proposed.
