Revert "Launch MiraclePtr on Renderer for IS_DESKTOP_ANDROID."

This reverts commit b87a6d2e30c48001b1c51db44bfb130953cea898.

Reason for revert: `is_desktop_android` is not allowed
neither in partition_alloc, nor in chrome. See:
https://chromium-review.googlesource.com/c/chromium/src/+/7547999/comment/7d646b43_0d3e9f0a/

Original change's description:
> Launch MiraclePtr on Renderer for IS_DESKTOP_ANDROID.
>
> This is launched on all platforms but Android, but IS_DESKTOP_ANDROID
> isn't yet fully launched. It should default to the higher protection
> rather than be disabled due to the same reasons as ANDROID.
