unpack-trees: add performance tracing
We're going to optimize unpack_trees() a bit in the following
patches. Let's add some tracing to measure how long it takes before
and after. This is the baseline ("git checkout -" on webkit.git, 275k
files on worktree)
performance: 0.056651714 s: read cache .git/index
performance: 0.183101080 s: preload index
