doc: add a release notes blurb on 1.16 linker improvements

Browse Source 
Add a draft version of a blurb on improvements to the linker. This
will need to be finalized later in the release since there are still
some additional changes to be made to the linker in 1.16.

Updates #40703.

TODO
This release includes additional improvements to the Go linker,
reducing linker resource usage (both time and memory) and improving
code robustness/maintainability. These changes form the second half
of a two-release project to
<a href="https://golang.org/s/better-linker">modernize the Go
linker</a>.
</p>
<p>
The linker changes in 1.16 extend the 1.15 improvements to all
supported architecture/OS combinations (the 1.15 performance improvements
were primarily focused on <code>ELF</code>-based OSes and
<code>amd64</code> architectures). For a representative set of
large Go programs, linking is 20-35% faster than 1.15 and requires
5-15% less memory on average for <code>linux/amd64</code>, with larger
improvements for other architectures and OSes.
</p>
<p>
TODO: update with final numbers later in the release.
