[Request] lf: add lfcd to shims

[laquazi]

lf manifest should add lfcd.ps1 and/or lfcd.cmd (there are also versions for other shells) to shims. lfcd provides a way to change working directory to the last directory in lf on exit. Which is a common use case.

The lfcd scripts are not included in the release archive. You would need to download them separately, and then:

• copy them in the shims folder during pre_install
• delete them from shims folder during pre_uninstall
