tools: add embeddingareasize arg to pvcreate and vgconvert

Browse Source 
To create an Embedding Area during PV creation (pvcreate or as part of
the vgconvert operation), we need to define the Embedding Area size.
The Embedding Area start will be calculated automatically by the tools.

This patch adds --embeddingareasize argument to pvcreate and vgconvert.
