philipp-spiess 816e7307de Escape JS theme configuration keys (#14739)
This PR fixes two issues related to how we tread JS theme keys in combination with CSS theme values:

1. When applying JS theme keys to our `Theme` class, we need to ensure they are escaped in the same way as reading CSS theme keys from CSS are.
2. When JS plugins use the `theme()` function to read a namespace that has values contributed to from the CSS theme and the JS theme, we need to ensure that the resulting set contains only unescaped theme keys.

For specific examples, please take a look at the test cases.
