Add a spec to ensure block-parameter destructuring does not emit unused-name warnings in verbose mode. The test evals a proc with parameters |key, (val1, val2)| and asserts it should_not complain(verbose: true), preventing false-positive warnings for inner destructured names.

This came up while working on jruby/jruby#9400. There is an MRI test for the method-definition case, but no test for destructured block arguments.
