Escape filenames in wxFileDataObject::GetDataSize/GetDataHere

Browse Source 
On wxGTK, wxFileDataObject::SetData calls g_filename_from_uri which
percent-decodes URIs. No corresponding percent-encoding was done in
wxFileDataObject::GetDataSize/GetDataHere. Use g_filename_to_uri instead in so
that filenames are properly escaped.

This commit also fixes the data being truncated if it contains non-ASCII
characters on wide-character builds, see the memcpy arguments in the original
code.
