Default background rendering has to be handled on the button renderer level
because of a specific markup for Outlook (bgcolor attribute). Default text color and paddings are
handled via CSS inlining. That's why they are tested in RendererTest
I used the same background color and font color as the one defined for the button
element in WP core theme.json, and I also used similar padding values
(In core they use "calc(0.667em + 2px) calc(1.333em + 2px)")

Add basic font families. For now, we use know-how from the current editor
and we use the same list of fonts as were used in the current editor

We don't reset font family on any level, so there is no need to
bubble the setting using a preprocessor and render the inline styles
explicitly in every block.
In this commit, I change how font-family settings are distributed/rendered
in the email renderer. In the new approach, we rely on class names defining font-family
and a generated CSS sheet with font-family definitions.
We apply the font-family CSS by inlining CSS rules for families in the later phase of
rendering after all individual blocks are processed.

codeception/verify 2.1 removed support for expect()->stringContainsString() so we need
to replace it with verify()->stringContainsString().

I envision the StylesController as the source of information about
styles settings in both the editor and renderer.
We will add email styles settings and these will be accessed in PHP via this service.
