builtin/config: introduce `color` type specifier

As of this commit, the canonical way to retreive an ANSI-compatible
color escape sequence from a configuration file is with the
`--get-color` action.

This is to allow Git to "fall back" on a default value for the color
should the given section not exist in the specified configuration(s).

With the addition of `--default`, this is no longer needed since:

  $ git config --default red --type=color core.section

will be have exactly as:

  $ git config --get-color core.section red

For consistency, let's introduce `--type=color` and encourage its use
with `--default` together over `--get-color` alone.
