import/get: escape non-pattern LFS path parts

[sisp]

• [x] ❗ I have followed the Contributing to DVC checklist.

• [ ] 📖 If this PR requires documentation updates, I have created a separate PR (or issue, at least) in dvc.org and linked it here.

I've fixed a bug related to passing literal/non-pattern path (parts) to the LFS prefetching function from scmrepo which would interpret them as Unix filename patterns and result in incorrect path filtering results. Now, the literal/non-path path (parts) are escaped.

See https://github.com/iterative/scmrepo/pull/355#discussion_r1589847222 for the preceding discussion.
