[WINESYNC] msi: Make MsiProcessMessage() RPC-compatible. 
Instead of passing a remote MSIHANDLE and creating a set of remote_Record*()
methods, we marshal the whole record as a wire struct. We do this for two
reasons: firstly, because chances are whoever is reading the record is going
to want to read the whole thing, so it's much less taxing on IPC to just pass
the whole record once; and secondly, because records can be created on the
client side or returned from the server side, and we don't want to have to
write a lot of extra code to deal with both possibilities.

The wire_record struct is designed so that we can simply pass the relevant
part of an MSIRECORD to the server.
