a11y: Support for Accessibility Settings

Description

<-- A clear and concise description of what the problem is. -->

I have looked into Rive docs and could not find a way to properly provide a11y description when using Compose (usually the AndroidView containing the Rive animation is skipped by Talkback) and it will also not respect animation speed set up in the system.

Expected behavior

• Properly support Talkback and ways to set content description or document that we should disable it.
• Respect the animation speeds, enabling/disabling set on the system.

Workaround

To work around the talkback issue I have wrapped the AndroidView containing the Rive Animation into a Box and set the semantics into it. Example:

Box(
        modifier = modifier
            .semantics { contentDescription = "description" },
        contentAlignment = Alignment.Center,
    ) {
        AndroidView(
            modifier = Modifier.fillMaxSize(),
            factory = {
                RiveAnimationView.Builder(it)
                    .setResource(animationResource)
                    .build()
            },
        )
    }

Start from the Compose integration that wraps RiveAnimationView.Builder in AndroidView, then inspect how the view interacts with Compose semantics and Android animation settings. Verify the result with TalkBack and system animation-speed and enable/disable settings; done means content descriptions are exposed and those settings are respected or documented.
