dix: initialize all screens before proceeding to gc's, root windows etc

Browse Source 
Current code walks along all screens and initializes screen resources,
then gc's, stipples, root windows for each of them, hence after
the first screen registering new private keys is no more possible.
This crashes modesetting driver if it is not initialized before others.

This patch makes screen resources for all screen initialize first, hence
all necessary private keys (including of the type PRIVATE_WINDOW) are
initialized before root windows are created.
