Expose UnitFactory to Python & add methods for conversion between two units

[Martyn Gigg]

A new tool for converting units for single values is being created. It requires that the unit factory is exposed to Python along with the addition of simple calls to be able to convert from one unit to another another without explicitly having to create each unit.

Improve VectorToNumpy return policy. Refs #5624

There are now two: VectorRefToNumpy & VectorToNumpy. The latter only allows clones as the return could be a return by value.

Makes it explicit that the object is modified.

This was done to allow some work by some work experience students but was not used.

Example usage:

from mantid.kernel import UnitConversion, DeltaEModeType
src_unit = "Wavelength"
src_value = 1.5
dest_unit = "Momentum"
        
l1 = l2 = twoTheta = efixed = 0.0
emode = DeltaEModeType.Indirect;
expected = 2.0*math.pi/src_value
   
result = UnitConversion.run(src_unit, dest_unit, src_value, l1, l2, twoTheta, emode, efixed)
