Documentation/gitpacking.txt: initial commit

Introduce a new manual page, gitpacking(7) to collect useful information
about advanced packing concepts in Git.

In future commits in this series, this manual page will expand to
describe the new pseudo-merge bitmaps feature, as well as include
examples, relevant configuration bits, use-cases, and so on.

Outside of this series, this manual page may absorb similar pieces from
other parts of Git's documentation about packing.

+NAME
+----
+gitpacking - Advanced concepts related to packing in Git
+
+SYNOPSIS
+--------
+gitpacking
+
+DESCRIPTION
+-----------
+
+This document aims to describe some advanced concepts related to packing
+in Git.
+
+Many concepts are currently described scattered between manual pages of
+various Git commands, including linkgit:git-pack-objects[1],
+linkgit:git-repack[1], and others, as well as linkgit:gitformat-pack[5],
+and parts of the `Documentation/technical` tree.
+
+There are many aspects of packing in Git that are not covered in this
+document that instead live in the aforementioned areas. Over time, those
+scattered bits may coalesce into this document.
