QTiffHandler: simplify use of TIFFWriteScanline() in write()

Fix the impedance mismatch between TIFFWriteScanline() wanting a void*
while QImage::scanLine() only provides pointer-to-const. Only one
caller correctly used a const_cast<uchar*>(), some were using C-style
casts to cast away const.

To fix, add a lambda, writeScanline, which takes the line by const
void*, and const-casts internally.

As a drive-by, remove the unneeded reinterpret_cast<uint32_t*>() (both
the new lambda and the old TIFFWriteScanline() take void*, so don't
need that cast).

Amends many. Because it is kinda invasive, pick to all active
branches, to not block real security fixes later on.

Pick-to: 6.11 6.8
