Duplicate copies of Google fonts in the repo

[fmarier]

We have two copies of the Muli and Poppins fonts in brave-core:

• https://github.com/brave/brave-core/tree/master/components/fonts
• https://github.com/brave/brave-core/tree/master/ui/webui/resources/fonts

Presumably one of these could refer to the other one.

This causes Muli to appear twice in brave://credits (#6881).

The two muli.css files aren't identical but from what I can see the only difference is that the one in ui/webui defines more sizes.

Same with the poppins.css files.

@fmarier It seems that test plan from brave/brave-core#4004 requires dev environment. Is there a way to test without it?

#6881 has already been verified. Maybe it is enough?

The alternative is to look at the various pages (listed in the PR) where we use the fonts and check that they "look right". I thought I wouldn't necessarily notice if the fonts had changed which is why I hacked the colors in my test.

Maybe someone with a good eye for fonts can double-check that everything looks right in Beta?

I tried to see but I am blind!
