GitPositionTransformer: Explicitly allow positions to not have a file

This change follows the same spirit as I2fa1b7bbb but focuses on the
file path.

Likewise, the follow-up change If8ed1e511 introduces an alternate
behavior to GitPositionTransformer for conflicts due to file deletions.

Positions without a file are mapped to patchset-level comments. The
chosen implementation allows to easily choose a different comment
location for such positions in the future if we decide that
patchset-level comments are not the best fit.
