Docs: Revise comments using “we” in various docblocks.

This updates some inline comments to better match the guidelines and recommendations set forth in the make/core and make/docs handbooks:

> In general, use second person in your documentation. Second person depicts a friendly tone, with a perfect focus on the reader. In addition to this, directly addressing the reader helps avoid passive voice; thereby preventing unwanted confusion. The word “we” should be avoided (...) unless its made very clear which group is speaking.
