User Story
As a user, I’d like to host Google Fonts locally to better control the fonts and improve LCP.

Acceptance Criteria

• The content of combined Google Fonts CSS file will be saved into the local CSS file, we'll name the CSS with the value of the original URL hash and save it into the path like we do for Used CSS: (2/e/4/h/aerw32eweq.css)
• The feature will handle V1 and V2 separately
• The feature will automatically copy combined CSS files in a sub-folder under wp-content, specifically /wp-content/cache/wp-rocket/fonts/google-fonts/
• The feature will rewrite URLs of the fonts found in the CSS file into the local path
• The feature will download fonts to the path that would preserve the original URL structure in the /fonts/ directory: /wp-content/cache/wp-rocket/fonts/google-fonts/fonts/s/caudex/v17/esDS311QOP6BJUr4yMKPtbo-Ew.woff2 (input: https://fonts.gstatic.com/s/caudex/v17/esDS311QOP6BJUr4yMKPtbo-Ew.woff2)
• The feature will create structure correctly for the multisites
