builtin/config: use OPT_CMDMODE() to specify modes

Browse source 
The git-config(1) command has various different modes which are
accessible via e.g. `--get-urlmatch` or `--unset-all`. These modes are
declared with `OPT_BIT()`, which causes two minor issues:

  - The respective modes also have a negated form `--no-get-urlmatch`,
    which is unintended.

  - We have to manually handle exclusiveness of the modes.

Switch these options to instead use `OPT_CMDMODE()`, which is made
exactly for this usecase. Remove the now-unneeded check that only a
single mode is given, which is now handled by the parse-options
interface.

While at it, format optional placeholders for arguments to conform to
our style guidelines by using `[<placeholder>]`.
