Update icon assets

[enerothseb]

Description

In this PR I've added a script which generates XML VectorDrawables so we can use the GDS Central Icons in XML views as well.

Pull new icon assets from Green repository. Noticed that some assets, e.g., BrandSwishWord wasn't generated properly using the s2c script.

Due to quality issues using the s2c script I removed the usage of this entirely, and rely on the generated VectorDrawables as single source of truth. The ImageVectors for Compose are now just a wrapper around the XML Drawables instead.
