windows-reactor improved dead code detection

[Kenny Kerr (kennykerr)]

The most effective way seems to be to use pub(crate) on functions.

Pull request overview

This PR updates windows-bindgen’s --minimal output and the reactor filter lists to improve trimming and dead-code visibility in generated bindings, then refreshes the relevant expected/generated outputs across reactor, canvas, and animation.

Changes:

• Emit pub(crate) methods (and delegate constructors) in --minimal bindings to make unused APIs detectable by dead_code within the generating crate.
• Make minimal-mode method inclusion overload-aware (match overload-disambiguated names only) and refine minimal filtering around activation/constructors.
• Update reactor filter lists and regenerate expected outputs/bindings to match the new codegen behavior.
