Parth Saini 3043094d71 imgproc: document per-code depth support on cvtColor/demosaicing src param ...

cvtColor's @param src promised 8U, 16U and 32F unconditionally, but the accepted
depths depend on the conversion code: CV_16U is rejected by COLOR_BGR2HSV,
COLOR_BGR2Lab, COLOR_BGR2Luv and the packed 16-bit codes, while COLOR_BGR2GRAY,
COLOR_BGR2XYZ, COLOR_BGR2YUV and RGB<->RGB accept it. That is what #26447
reported.

State it on @param src and point at the [8U]/[16U]/[32F] markers already
documented on ColorConversionCodes. The @note only said the source "must be of
an appropriate type", which is now redundant, so drop it from both functions.

demosaicing has the same problem: the Variable Number of Gradients codes accept
8-bit input only, while the other Bayer codes also accept 16-bit.

Fixes #26447
