Revert "[Paint Preview] Pre-warm compositor"

This reverts commit 3480cbb1182facf5dd38e4a5687ecd2a16b83908.

Reason for revert: This caused some performance/memory regressions that
are far larger than expected.

Original change's description:
> [Paint Preview] Pre-warm compositor
> 
> This CL adds the ability to pre-warm a compositor process for use by
> paint preview show-on-startup.
> 
> 1. The compositor is started when native is initialized if the
>    experiment is enabled.
> 2. Depending on the situation the compositor is then used or killed.
>    a. Compositor is used: disconnect handler is updated and it is used
>       as if there was a compositor already.
>    b. Compositor is not used: the process is killed immediately.
> 
> This moves initialization of the compositor service up to O(100 ms)
> earlier (in local tests).
