Omar Emara 8ade574b9f Shading: Retain alpha in Mix Color shader code 
The Mix Color shader node does not retain the alpha channel of the first
input in both the Linear Light and Soft Light modes, while it is retain
for other modes. Further, result clamping also ignores the alpha due to
using the vector clamp function, which introduces implicit conversion
that removes the alpha.

This does not matter for EEVEE because it does nothing with the alpha
channel. But the code will now be shared with the compositor, which does
care about the alpha channel. So adjust the code accordingly to retain
the alpha in those cases.
