45627: vcs_info git: Under git-am(1) conflicts, pass to the gen-applied-string hook information on already-applied patches.

Browse source 
The hook already receives information about the current (topmost
applied) patch and, if the get-unapplied style is set, about future
(unapplied) patches.

Tested in the Functions/VCS_Info/test-repo-git-rebase-apply scenario,
after manually converting the rebase to a «git am».  (Specifically,
I ran:
    mkdir d
    git rebase --abort
    git format-patch rebase_from_this..HEAD -o d
    git checkout rebase_onto_this
    git am d/*
.)
