doc/go1.16: add multiple release notes for the go command

Browse Source 
Added notes for:

* go test -c and -i flags used with unknown flags
* GO111MODULE=on by default
* GOVCS
* Dropped requirements on excluded versions

Removed TODOs for documentation on the retract directive and
'go install pkg@version'. These pages will be written after the beta.

<h4 id="govcs"><code>GOVCS</code> environment variable</h4>
<p><!-- golang.org/issue/266420 -->
<code>GOVCS</code> is a new environment variable that limits which version
control tools the <code>go</code> command may use to download source code.
This mitigates security issues with tools that are typically used in trusted,
authenticated environments. By default, <code>git</code> and <code>hg</code>
may be used to download code from any repository. <code>svn</code>,
<code>bzr</code>, and <code>fossil</code> may only be used to download code
from repositories with module paths or package paths matching patterns in
the <code>GOPRIVATE</code> environment variable. See
<a href="/cmd/go/#hdr-Controlling_version_control_with_GOVCS"><code>go</code>
<code>help</code> <code>vcs</code></a> for details.
