Map shutdown ANR

What happened?

We're seeing some ANRs during map shutdown in a multi-map environment. When MapLibreSurfaceView.requestExitAndWait() is called during cleanup it waits for the RenderThread to exit and that seems to deadlock in eglDestroyContext.

Steps to reproduce

Unknown

Renderer

OpenGL (choose this if you are unsure)
