lib: xc7series: convience constructor for Configuration

Configuration's original constructor expects Span<uint32_t>s as part of
the map to avoid copying the actual frame data.  In tests or any other
place that needs to directly construct a Configuration, the caller will
already have a map with vector<uint32_t> to hold the actual frame data.
This new constructor just wraps those vectors in Spans.
