refactor(google): add a lot of styles to ogs, use and add gm3 tokens for modern component styling

[WalkQuackBack]

🔧 What does this fix? 🔧

As of now, the ogs Google dialogue is not themed very consistently and a lot of elements are unthemed.

Before:

Colour on focused border and elevated card background

Accent colour, state layer on hairline/outlined button, accent colour, state layer, background on tonal button, accent colour on icons, background and text on badges, text on dismiss icon

After:

This refactor attempts to make styling more consistent by directly using and modifying the CSS bundles that are provided by Google, decreasing the chance that styles are missed and making the look more consistent.
