Fix #77272: imagescale() may return image resource on failure

`_gdScaleHoriz()` and `_gdScaleVert()` may fail, but don't signal
failure since they are void functions. We change that according to
upstream libgd.

We also remove the unused `Scale()` function, which doesn't exist in
upstream libgd either, right away.

Fixed bug #65148 (imagerotate may alter image dimensions)

We apply the respective patches from external libgd, work around the
still missing `gdImageClone()`, and fix the special cased rotation
routines according to Pierre's patch
(https://gist.github.com/pierrejoye/59d72385ed1888cf8894a7ed437235ae).

We also cater to bug73272.phpt whose result obviously changes a bit.

Fixed bug #75139 (libgd/gd_interpolation.c:1786: suspicious if ?)

We back-port https://github.com/libgd/libgd/commit/dd48286 even though
we cannot come up with a regression test, because the erroneous
condition appears to be impossible to trigger.

We also parenthesize the inner ternary operation to avoid confusion.
