pp/cpp's spreadconstraints are not validated correctly

[whitewindmills]

What happened:
Error pp/cpp's spreadconstraints can be create and affect the scheduling process.

What you expected to happen:
minGroups and maxGroup should not be less that zero, and maxGroup should also get default value(I think it should be minGroups)
How to reproduce it (as minimally and precisely as possible):
Create pp or cpp with incorrect minGroups and maxGroup.
Anything else we need to know?:

Environment:

• Karmada version:
• kubectl-karmada or karmadactl version (the result of kubectl-karmada version or karmadactl version):
• Others:

Thanks, It makes sense to me. I'll look at #3232 later.
