[#264] Make `dfsTraverseValue` parameterized by `DfsSettings`

Description

Problem: Unlike dfsTraverseInstr, dfsTraverseValue doesn't provide any way to specify how effects should be applied (see DfsSettings).

And because of that when it encounters a value with instructions it doesn't respect DfsSettings to full extent (e. g. if there is a pair of two lambdas).

Solution: Make dfsTraverseValue parameterized by DfsSettings.
