Allow more Python scalar conversions

Browse Source 
PR python/18352 points out that the gdb Python code can't convert an
integer-valued gdb.Value to a Python float.  While writing the test I
noticed that, similarly, converting integer gdb.Values to float does
not work.  However, all of these cases seem reasonable.
