Extract scope synchronization from configure scope include

The android specific scope synchronization block was right after
the code block that demonstrated setting a user, and before the
code block that unsets a user. This made reading the documentation
confusing, so I extracted a new included page and added a new
platform section that only supports android to hold it.

-If you want to set context data in the Java layer, then receive that context data when a native (C/C++) crash happens, you need to synchronize the Java `Scope` with the native `Scope`. This feature was introduced in version `3.0.0` of the Android SDK and requires an opt-in:
-
-```xml {filename:AndroidManifest.xml}
-<application>
-    <meta-data android:name="io.sentry.ndk.scope-sync.enable" android:value="true" />
