Option to disable or configure `svelte-announcer`

Describe the problem

Currently, the svelte-announcer element always gets injected into the webpage, and there is no way to disable it or override its behavior.

Describe the proposed solution

It would be nice to be able to disable it or control it in some form, for example if we wish to have more fine-grained ARIA announcements.

Additional Information

For anyone currently looking to remove svelte-announcer and implement their own, we use this preprocessor as a workaround to get rid of it in svelte.config.js:

    preprocess: [
        {
            name: "strip-announcer",
            markup: ({ content: code }) => {
                code = code.replace(
                    /<div id="svelte-announcer" [\s\S]*?<\/div>/,
                    '<svelte:component this={null} />'
                );

                return { code }
            }
        },
        // ...
    ],
    // ...

Start by reviewing the svelte.config.js workaround and tracing where the svelte-announcer element is injected. Define whether the configuration should disable the announcer, replace it, or expose behavior controls, then verify that custom ARIA announcements remain possible without the workaround.
