v2.45.2.vfs.0.2: performance regression in pathspec checkouts

[derrickstolee]

Setup

• Which version of microsoft/git are you using? Is it 32-bit or 64-bit?

$ git --version --build-options

v2.45.2.vfs.0.2

Are you using Scalar or VFS for Git?

VFS for Git

If VFS for Git, then what version? (latest)

• Which version of Windows are you running? Vista, 7, 8, 10? Is it 32-bit or 64-bit?

Details

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

git restore .

This used to be fast, but now is slow.

Note: I'm passing this report from an internal user. I've recommended that they use git reset --hard as a way that should avoid the current regression as well as communicating to Git the full expectation of what is going on, but this performance regression should be avoided. Unfortunately, this also means the issue fixed by #658 is not fully fixed.
