feat(tvix/glue/derivationStrict): support __structuredAttrs r/7376
This adds support to handle the __structuredAttrs argument, which can be passed to builtins.derivationStrict. If __structuredAttrs is passed, and set to true, most of the arguments passed to builtins.derivationStrict are not simply coerced to a string and passed down to "environments", but instead kept in a more structured fashion. Inside ATerm, which is what's relevant as far as path calculation is concerned, a virtual `__json` environment variable is present, containing these structured values. Inside Builds, these structured values are not made available as an environment variable, but a JSON file (and source-able bash script). This will need to be respected once we start emitting BuildRequests, and for that we can probably just parse the `__json` key in Derivation.environment again - or keep this additionally in non-serialized form around during Evaluation. No matter what, this is left for a followup CL. The existing handle_derivation_parameters and populate_outputs helper function were removed, as __structuredAttrs causes quite a change in behaviour, and so handling both in the same place makes it more readable. There's some open questions w.r.t. string contexts for structured attrs itself. A TODO is left for this, but at least path calculation for individual structured attrs derivations are correct now. Part of b/366. Change-Id: Ic293822266ced6f8c4826d8ef0d2e098a4adccaa Reviewed-on: https://cl.tvl.fyi/c/depot/+/10604 Tested-by: BuildkiteCI Reviewed-by: raitobezarius <tvl@lahfa.xyz>
