feat(tvix/eval): implement nested '?' operator r/4496
Implements the nested presence check operator for attribuet sets by
traversing the chain of lookups through instructions that push/pop
sequentially deeper attribute sets onto the stack.

Note that this commit introduces a bug in case of nested attributes
not being found, which is fixed in a later commit.
