It appears adding "mask[i % 5]" to BOOLEAN_MASK_GENERATORS/boolMaskUnaryOpProvider may have exposed a potential bug in ByteVector.reduceLanes(VectorOperators.MUL, vmask).  I have made the following updates to separate the "ByteVector.reduceLanes(VectorOperators.MUL, vmask)" issue from this PR.

(1) Removed "mask[i % 5]" from BOOLEAN_MASK_GENERATORS
(2) Restored boolUnaryOpProvider for reduction/Unit-BoolReduction-op.template
