Block-Editor: Enhance FontFamily Component

[Utsav-Ladani]

What?

• This PR changes the FontFamily component in the block-editor package.

Why?

• In the current version, the font list becomes too much taller (same as the screen width) in Chrome because SelectControl uses the <select> HTML tag.
• If we use CustomSelectControl then the list will not become taller, it get a scrollbar if necessary and our UI stays the same for all different browsers.

How?

• It replaces SelectControl with CustomSelectControl to solve the issue.
• The CustomSelectControl uses a custom interface for the select menu, however, SelectControl uses the default <select> tag which is different in all browsers.

Testing Instructions

1. Create a post.
2. Add paragraph block.
3. Write some text to it.
4. Select the block and open the sidebar panel.
5. Enable font family in the Typography panel.
6. Try to select different fonts from the drop-down box and see the result.

Great work!
I have enabled Jetpack Google Fonts (beta) to have a scrollable dropdown of fonts in the Font Family field. It works great, having a consistent experience across browsers.
