JIT: invoke nullable box optimizations earlier (#32269)

Move the logic in `fgMorphRecognizeBoxNullable` into `gtFoldExprSpecial`
so it can be invoked earlier. This may prevent the original struct
from becoming address exposed and allow subsequent optimizations when the
`hasValue` field has a known value.

Fixes #31661.
