Vincent Ambo 3a67f91228 fix(tvix/eval): ? operator should use OpAttrsOrNotFound 
Using `OpAttrSelect`, the ? operator will fail when encountering a
nested value that is not an attribute set.

This however breaks valid code, such as:

  { bs = 42; } ? bs.a.b

The fix is simply to use the same operator used in the `or` statement,
which leaves a sentinal on the stack if a field is not found or the
value is not an attribute set.

License structure

All code implemented for Tvix is licensed under the GPL-3.0, with the exception of the protocol buffer definitions used for communication between services which are available under a more permissive license (MIT).

The idea behind this structure is that any direct usage of our code (e.g. linking to it, embedding the evaluator, etc.) will fall under the terms of the GPL3, but users are free to implement their own components speaking these protocols under the terms of the MIT license.
