LiveAnnouncer's announce is not working on the first trigger for NVDA and JAWS

### Provide a general summary of the issue here

When using the announce method of [LiveAnnouncer](https://github.com/adobe/react-spectrum/blob/main/packages/%40react-aria/live-announcer/src/LiveAnnouncer.tsx) in @react-aria for the very first time, the message is not being announced as expected. However, subsequent triggers seem to work as expected. This issue is specific to NVDA and JAWS; it functions correctly with VoiceOver.

### 🤔 Expected Behavior?

The announce method should work consistently across all triggers, starting from the first one.

### 😯 Current Behavior

The message is not announced during the first trigger of the announce method, but it works on subsequent triggers.

### 💁 Possible Solution

- There's a potential race condition between the Assistive Technology and the creation of the live area.
- A suggested solution is to create the live region during the load time of the LiveAnnouncer module instead of waiting until the first invocation of announce.
