rustdoc: add optional woff2 versions of Source Serif and Source Code

This provides woff2 versions of Source Serif and Source Code similar to how #82545 provides woff2 versions of Fira Sans. The total byte count for the six files (three for each font family) is reduced by 25% from 476 KiB to 358 KiB.
