Allow `GoogleMap` opt out of keyboard focus traversal

[svendroid]

Summary

Please expose an official way to make GoogleMap opt out of keyboard focus traversal.

Problem

In our app, GoogleMap is used as a background, which is overlayed by different content e.g. sheets. In accessibility mode the user can control the map via additional ui e.g. zoom-buttons, pan-buttons, etc.

In this setup, the map itself should not receive focus during keyboard traversal because to the user it seems like the focus is hidden behind the overlaying content. It seems like a bug that the map is focusable because you cannot interact with it as a keyboard user and therefore the keyboard focus gets hidden.

Compose focus APIs such as:

Modifier.focusProperties { canFocus = false }

does not work.

Expected behavior

A supported API such as:

GoogleMap(
    modifier = Modifier.fillMaxSize(),
    focusable = false,
)

Similiar to mergeDescendants for controlling talkback.

Reproduction

Place GoogleMap behind several focusable Compose controls
Traverse with Tab / Shift+Tab
Focus still lands on the map (see video, the background with the map gets dark)

Example

For a minimal example see https://github.com/user-attachments/assets/85a14302-5da9-42c3-a10c-9b0fc75386f3. The app is traverserd with tab from a keyboard. The background with the map should not receive focus, only the buttons and the zoom buttons.
