documentation: Simplify yocto_git links

The yocto_git external link directive is modified to include the
`/cgit/cgit.cgi` element of the URL so that we can simplify the links in
the text.

Manual links to git.yoctoproject.org are converted to use the yocto_git
directive where possible. Note that this directive can't be used in some
places such as example code.
