drm_hwcomposer: Rework HWC frontends buffer management Change summary: - Use BufferInfo instead of native_buffer to configure the HwcLayer. - Extend buffer properties with slot info. - Provide fence and active slot ID separate from the buffer. - Move swapchain tracking into HWC2. HWC3 doesn't need that. Why: - Support more flexible resource management control from the frontend side, which is required by HWC3 API. - Move more Android-specific data types to the frontend module.
