spoolss: [2/2] Implement EnumPorts (Forward to winspool.drv)

[Detlef Riekenberg]

Native Printmonitors need this from spoolss.dll

The most compatible way would be:
- Implement the Printprovider in localspl.dll
- Call all Printprovider from spoolss.dll  
- Do RPC-Calls to the the spooler from winspool.drv 

We can take this short path



Changelog:
spoolss: [2/2] Implement EnumPorts (Forward to winspool.drv)

The Documentation are my own words
(Also for spoolss [1/2])
