Introduce a new method `gtTryRemoveBoxUpstreamEffects` to capture the logic for cleaning up after a dead value type box into a utility. Call this from `gtFoldExprSpecial` and now also from the inliner when it finds a dead box argument. Also remove the useless `fgExpandInline` field and associated `fgIsInlining` method, as the jit never set the field to true. No diffs from the refactoring. The inliner case kicks in in 3 places in the test tree. Closes #13136.

I'm mildly surprised you're checking IsBoxedValue here rather than asserting it here and expecting callers to check.
