combine-diff: factor out stat-format mask
There are several conditionals in the combine diff code that check if
we're doing --stat or --numstat output. Since these must all remain in
sync, let's pull them out into a separate bit-mask.
Arguably this could go into diff.h along with the other DIFF_FORMAT
macros, but it's not clear that the definition of "which formats are
stat" is universal (e.g., does --dirstat count? --summary?). So let's
keep this local to combine-diff.c, where the meaning is more clearly
"stat formats that combine-diff supports".
