Add an off-thread preparation step for downloaded vector fonts so WOFF2 resources can be decompressed before LibWeb tries to create a typeface from them. This avoids doing the conversion work on the main thread during @font-face loading. Expose raw WOFF2-to-TTF conversion from LibGfx's WOFF2 loader and use that from the new preparation path. Keeping the libwoff2 integration in LibGfx preserves the layering between LibWeb and the third-party decoder while still letting LibWeb schedule the work off-thread.
