Subject: [PATCH] STYLE: Add `const` to TransformPhysicalPointToIndex results
 in "Review"

Declared local "IndexType" variables in "Nonunit/Review" that are initialized
by the result of a TransformPhysicalPointToIndex(point) call `const`.

Follow-up to commit 49ece7f60841b79c306b9a709ffcee228ce9c347
"COMP: Fix TransformPhysicalPointToIndex `nodiscard` warnings"
