Returns a valid theme.json as provided by a theme.
Description
Unlike get_raw_data() this returns the presets flattened, as provided by a theme.
This also uses appearanceTools instead of their opt-ins if all of them are true.

/*
* The array_replace_recursive algorithm merges at the leaf level,
* but we don't want leaf arrays to be merged, so we overwrite it.
*
* For leaf values that are sequential arrays it will use the numeric indexes for replacement.
* We rather replace the existing with the incoming value, if it exists.
* This is the case of spacing.units.
*
* For leaf values that are associative arrays it will merge them as expected.
* This is also not the behavior we want for the current associative arrays (presets).
* We rather replace the existing with the incoming value, if it exists.
* This happens, for example, when we merge data from theme.json upon existing
* theme supports or when we merge anything coming from the same source twice.
* This is the case of color.palette, color.gradients, color.duotone,
* typography.fontSizes, or typography.fontFamilies.
*
* Additionally, for some preset types, we also want to make sure the
* values they introduce don't conflict with default values. We do so
* by checking the incoming slugs for theme presets and compare them
* with the equivalent default presets: if a slug is present as a default
* we remove it from the theme presets.
