commitctx: document the manifest writing function

Same spirit as for `_filecommit` lets document the input and output before
making any change or improvement.

This is part of a larger refactoring/cleanup of the commitctx code to clarify
and augment the logic gathering metadata useful for copy tracing. The current
code is a tad too long and entangled to make such update easy. We start with
easy and small cleanup.
