Allow setting a parameter to raise gdb.GdbError

Browse Source 
A convention in the Python layer is that raising a gdb.GdbError will
not print the Python stack -- instead the exception is treated as any
other gdb exception.

PR python/18852 asks that this treatment be extended the the
get_set_value method of gdb.Parameter.  This makes sense, because it
lets Python-created parameters act like gdb parameters.
