Set the requires-full-index to false for "diff-tree".

Add a test to ensure that the index is not expanded whether the files are outside or inside the sparse-checkout cone when the sparse index is enabled.

The `p2000` tests demonstrate a ~63% execution time reduction for 'git check-attr' using a sparse index.

Test before after ----------------------------------------------------------------------- 2000.106: git check-attr -a f2/f4/a (full-v3) 0.05 0.05 +0.0% 2000.107: git check-attr -a f2/f4/a (full-v4) 0.05 0.05 +0.0% 2000.108: git check-attr -a f2/f4/a (sparse-v3) 0.04 0.02 -50.0% 2000.109: git check-attr -a f2/f4/a (sparse-v4) 0.04 0.01 -75.0%
