Add a section on providing global level configuration from the
layer.conf file. Since this file is parsed at an earlier stage in the
parsing process, it's not possible to combine bb.utils.contains and
{DISTRO,MACHINE}_FEATURES to conditionally set some configurations.
This patch documents:
- First that this file can be used for providing such configuration.
- Then demonstrate how to conditionally provide them, using a technique
that is currently used in meta-virtualization
(https://git.yoctoproject.org/meta-virtualization/tree/conf/layer.conf#n50).
Fixes [YOCTO #12688].

As reported by "make sphinx-lint"
Tabs are even removed in Makefile examples,
as Sphinx turns them to spaces anyway in the generated output.

To simplify the style, replace "Following is" and "Following are"
by "here is" and "here are", sounding more natural.
In some cases, also go further by simplifying "Here are/is xxx"
by "xxx are/is" when the "are" or "is" are not two far at
the end of the sentence.
In some cases too, completely remove the sentence, when
it's redundant with the preceding title.

As discussed before with Richard Purdie, the code supports this but the documentation does not.
Developers in general will not notice this or focus on it because they do not mess with the
layer.conf template file, but in my opinion I think more details can help.

Reusing content from the master branch which underwent
this change earlier.
This change makes it much easier to backport manual
updates to the kirkstone LTS branch.
To make the change and future updates simpler, reused file contents
from master, only excluding changes which don't apply to kirkstone.
