RFR: 8377568: DataBuffer constructors and methods do not specify required exceptions [v3]

[Phil Race]

> This fix updates DataBuffer subclasses to actually adhere to their stated specifications by rejecting certain invalid parameters for constructors and getters and setters.
> A new egression test for each of the constructor and getter/setter cases is supplied.
> 
> No existing regression tests fail with this change, and standard demos work.
> 
> Problems caused by these changes are most likely to occur if the client has a bug such that 
> - a client uses the constructors that accept an array and then supplies a "size" that is greater than the array.
> - a client uses the constructors that accept an array and then supplies a "size" that is less than the array and then uses getter/setters that are within the array but outside the range specified by size. 
> 
> Since very few clients (and just one case in the JDK that I found) even use these array constructors the changes are unlikely to make a difference to clients.
> 
> A CSR will be submitted.
