Remove usingnamepace usage

[hazeycode]

Resolves #3

[Copilot]

Pull request overview

This PR removes usingnamespace-based COM method mixins across the Windows bindings, aligning the codebase with Zig’s direction in ziglang/zig#20663 and keeping the bindings usable on newer Zig versions.

Changes:

• Replaced usingnamespace ...Methods(@This()) patterns with explicit pub inline fn ... wrappers for COM/IUnknown-style interfaces across the Windows bindings.
• Updated D3D12 usage sites to match “out-parameter” getter signatures (e.g., GetDesc(&desc), Get*HandleForHeapStart(&handle)).
• Added a new src/meta.zig helper intended to generate interface/VTable types via reflection.

GetBindingProperties previously returned BINDING_PROPERTIES by value (convenience wrapper around the out-parameter vtable call). It now requires the caller to allocate/pass a pointer and returns that pointer, which is an API-breaking change for consumers and makes common call sites more verbose. Consider restoring the by-value helper (and optionally adding a separate GetBindingPropertiesPtr/FillBindingProperties variant) to avoid breaking callers.

Intentional. These are supposed to be thin COM bindings not a wrapper.
