Add Font Family dropdown to individual blocks in global Styles

[bradhogan]

What problem does this address?

Currently, you can add as many fonts as you'd like to your theme, register them in the theme.json and functions file and those fonts will appear in the global Styles > Typography > Font Family dropdown. However, if you want to make a global edit to a specific block (Quote block for example), you can go to Styles > Blocks > Quote > Typography > and you can change size, line-height and letter spacing, but not the font family.

What is your proposed solution?

It would be great to add a font family section to the global styles typography options for individual blocks. If I wanted my entire site to use a sans-serif type for heading and body but add a little flare and have the quote use a monospace font, I'd like to be able to change that in the global Styles and not in the theme files.

Some blocks do have support for font families here (such as post title and site title), but I think more blocks definitely need to add support for this feature.

For example, here is a PR I just opened to enable it for the core/heading block.

I don't think the plan is for all blocks to support this, but at the very least a list of blocks that make sense (I think your example of the quote block would make sense as well!)
