doc: describe mergetool configuration in git-mergetool(1)

In particular, this describes mergetool.hideResolved, which can help users discover this setting (either because it may be useful to them or in order to understand mergetool's behavior if they have forgotten setting it in the past). Tested by running make -C Documentation git-mergetool.1 man Documentation/git-mergetool.1 and reading through the page.
