Because we want to have all editor configurations in theme.json, I moved heading font sized to theme.json and removed redundant filters.

I want to avoid the SettingsController becoming some kind of a god class
so in this step, I extracted themejson-related stuff to an extra class.
In the future, we should also move methods for manipulating CSS to a helper.

Initially, I tried to place the definition to theme.json
(It could set it in styles.block.core/heading or styles.elements.h1...)
It was not possible to use theme.json because of the fluid typography
feature which, when enabled for a site, causes font sizes to being
converted to the fluid definition (clamp(x, y, z)) and which
is not usable for an email due to very little client support.
We need to make some changes in Gutenberg to be able to disable the feature.
Currently, the code for generating font sizes in CSS generated from the theme.json
looks directly at the global settings of the site.

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)")

The method was loading both themes separately. This commit changes
the behavior so that it uses only the email theme which contains
also the core theme settings.
Instead of modifying the core theme settings in PHP we can now
move these settings into the email editor theme, which is merged
into the core theme.

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.
