Split crates/wayland/src/winit.rs (889 lines) into winit/

Pure reorganization, no behavior change - verified by diffing the
function-name and struct-name sets before/after (both identical) plus
a full cargo test pass. mod.rs keeps the module doc comment, imports,
WaylandPlatform's struct definition, and TARGET_FRAME_TIME, plus mod
declarations. The rest splits by concern:

- connect.rs: connect(), the ~200-line setup/init function.
- run.rs: accept_clients, pump_winit - the small per-poll pair.
- render.rs: render_frame, the per-frame render loop (left as one
  intact ~330-line function, same reasoning as udev's render.rs: its
  structure is deliberate and already documented inline, not a target
  for further decomposition in a pure reorganization pass).
- capture.rs: capture_offscreen, the screencopy path.
- events.rs: handle_winit_event.
- platform.rs: `impl Platform for WaylandPlatform`.

No tests module existed in the original file, so none was split out.

A handful of methods/functions (accept_clients, pump_winit,
render_frame, capture_offscreen, handle_winit_event) went from private
to pub(super): called across what are now sibling submodules, which
Rust's privacy model doesn't let see each other's private items.
