Imprecise definition of how parameters are handled in `MethodLinkBuilderFactory.linkTo(…)` methods

[odrotbohm]

MethodLinkBuilderFactory.linkTo(…) methods taking Class and Method parameters implicitly assume that they're called with a parameter array of a length matching the number of expected parameters on the method. This assumption comes from WebMvcLinkBuilderFactory.linkTo(Object) just calling ….next() on theIterator of the received parameters.

This was reported as a behavioral change in Blazebit/blaze-persistence#1363 and likely introduced by the fix for #1598.

We should tighten the contract by adding additional methods that do not take a varargs parameter and let those create an Object[] based on the number of parameters the handed in method has. The methods actually taking parameters could then be tightened to verify the parameter array length so that mismatches in the two would still be covered if parameters are given in the first place.
