Support LFS include/exclude

[alex-statsig]

Currently git LFS seems to be all-or-nothing in the checkout action. Would it be possible to support include/exclude paths similar to the underlying git command (ex. https://www.atlassian.com/git/tutorials/git-lfs)? This would be valuable in monorepo setups to avoid downloading LFS files for other apps (and thus decrease LFS bandwidth usage).

From what I can tell, it seems like the lfsFetch command could fairly easily propagate some setting for lfs-exclude here

I think this duplicates #165 on the bandwidth issue. The workaround there can be adjusted to include -X and -I options for git lfs pull.
