wined3d: Floating point shader constant setting.

Browse source 
Test how shader constant limits are checked in Set*ShaderConstantF.
The vertex shader tests it based on the limits reported in the caps,
the pixel shader tests tries to find the limit manually because I
could not find a cap structure member specifying the pixel shader
constant limit.

Set*ShaderConstantF returns an error as soon as start or start + count
are bigger than the constant limit.
