Fix colormap functions when N is not of class double (bug #44070)
* autumn.m, bone.m, cool.m, copper.m, cubehelix.m, gray.m, hsv.m, ocean.m,
rainbow.m, spring.m, summer.m, winter.m: cast N to double since in this
colormap functions, N is used directly used in the operations and ends up
casting colormap to something else. Note that a colormap MUST be of class
double. Also, if N is an integer class, all values in colormap end up 0
or 1. Also simplify code for input checking by declaring default on function
signature line.
* flag.m, gmap40.m, hot.m, jet.m, lines.m, pink.m, prism.m, white.m: simplify
input check like the other colormap functions.
* test/colormaps.tst: add new test file to test all colormaps at once.
* test/Makefile.am: add new test file to build system.
