Reduce tamagui css file size

None of the configured color themes are currently in use. It makes sense to drop including them and instead let developers opt into including them. Note that a v3 of tamagui's theme builder will be released soon and my provide other optimization options. Also dropping use of the Inter font in place of system fonts.
