RFR: 8368729: Add appropriate checks in java.awt.image.Kernel constructor

[Jayathirth D V]

`java.awt.image.Kernel` constructor doesn't validate all input values and we need to add appropriate checks.
A new test is also added to make sure we appropriate exception when invalid values are passed.

This will also need a CSR.
