Ifpack2: fixing instantiation in BlockRelaxation valid parameter list

James Willenbring requested to merge lucbv:Ifpack2_fix_blockrelaxation_parameter_validation into develop

Created by: lucbv

the parameter "partitioner: coordinates" was not instantiated correctly in getValidParameters which then caused an issue if one uses a non default build of Trilinos. This should be fixed with the changes in this commit.

@trilinos/ifpack2

Description

Simply modifying the template parameters in Ifpack2::BlockRelaxation::getValidParameters() to have the coordinates multivector consistently templated with the matrix type

Motivation and Context

This will allow MueLu users to interface properly with Ifpack2 line detection capabilities.

How Has This Been Tested?

A new test is added in MueLu that uses this feature. The new test is now passing.
