tdf#109169 export Type encoded shading to OOXML

A shape might have the shading information not in commands in the
enhanced-path, but generated in ctor of EnhancedCustomShape2d from the
Type value of the shape. This shading information is a 32 bit value
with first the number of the shadings and then the shadings. A shading
is encoded with 1,2,3,4,5,6,7 for lighten 10 to 70 and 8,9,a,b,c,d,e,f
for darken -80 to -10.

To get this information from EnhanceCustomShape2d I have made its
method GetLuminanceChange() public.

Because OOXML only has darken, darkenLess, lighten and lightenLess our
values are mapped:
-10, -20, -30 to darkenLess
-40, -50, -60, -70, -80 to darken
10, 20, 30 to lightenLess
40, 50, 60, 70 to lighten

The bupreport mentions only 'Octagon Bevel' and 'Diamond Bevel'. But
the patch fixes missing shading for shapes of Types 'ActionButton*'
as well. Such shapes come in from MS binary import.
