Track binary driver/installer payloads via Git LFS

Reverses the earlier '.gitignore + filter-repo' approach: 849 binary
files (.cab .sys .dll .inf .cat .exe .msi .msp .mst .jar .icm .chm
.jsa .prn .dl_ .da_ .ch_ .in_ .ex_ .ds_, case-insensitive) now flow
through LFS (.gitattributes), while the repo tree stays small.

Rationale: fresh clones should be buildable without out-of-band driver
fetches. LFS keeps the blobs on Gitea's LFS storage; the repo ships
pointer files (~140 bytes each).
