fix(tvix/eval): force left argument of `?` before checking for attrs r/4849
OpAttrsIsSet and OpAttrsTrySelect will fail silently if the attribute
set value on the stack is actually a thunk, so we need to make sure to
force at every step of the way.

Emitting the force instructions in the compiler because it is easier to
add, but maybe the VM should do this when handling the relevant opcodes?
Comments welcome.
