2274f63453 Get rid of basicDerivation::findOutput
It's a tiny function which is:

 - hardly worth abstrating over, and also only used once.

 - doesn't work once we get CA drvs

I rewrote the one callsite to be forwards compatable with CA
derivations, and also potentially more performant: instead of reading in
the derivation it can ust consult the SQLite DB in the common case.

230c9b4329 Change types to prepare the way for CA derivations
We've added the variant to `DerivationOutput` to support them, but made
`DerivationOutput::path` partial to avoid actually implementing them.

With this chage, we can all collaborate on "just" removing
`DerivationOutput::path` calls to implement CA derivations.

fedfc913ad Use more std::visit to prepare for new variant
N.B. not using `std::visit` for fetchurl because there is no attempt to
handle all the cases (e.g. no `else`) and lambda complicates early
return.

8e0d0689be Only store hash of fixed derivation output
we don’t need a full storepath for a fixedoutput derivation. So just
putting the ingestion method + the hash is sufficient.

af95a7c16b Add name to BasicDerivation
We always have a name for BasicDerivation, since we have a derivation
store path that has a name.

045b07200c Remove Store::queryDerivationOutputNames()
This function was used in only one place, where it could easily be
replaced by readDerivation() since it's not
performance-critical. (This function appears to have been modelled
after queryDerivationOutputs(), which exists only to make the garbage
collector faster.)

832bd534dc Store parsed hashes in DerivationOutput
It's best to detect invalid data as soon as possible, with data types
that make storing it impossible.

bcde5456cc Flip dependency so store-api.hh includes derivations.hh
I think it makes more sense to define the data model (derivations),
before the operations (store api).

f1cf3ab870 hashDerivationModulo: Generalize for multiple fixed ouputs per drv
See documentattion in header and comments in implementation for details.

This is actually done in preparation for floating ca derivations, not
multi-output fixed ca derivations, but the distinction doesn't yet
mattter.

Thanks @cole-h for finding and fixing a bunch of typos.

2be64efb02 Generalize isFixedOutput in preparation for CA drvs
Today's fixed output derivations and regular derivations differ in a few
ways which are largely orthogonal. This replaces `isFixedOutput` with a
`type` that returns an enum of possible combinations.

bbe97dff8b Make the Store API more type-safe
Most functions now take a StorePath argument rather than a Path (which
is just an alias for std::string). The StorePath constructor ensures
that the path is syntactically correct (i.e. it looks like
<store-dir>/<base32-hash>-<name>). Similarly, functions like
buildPaths() now take a StorePathWithOutputs, rather than abusing Path
by adding a '!<outputs>' suffix.

Note that the StorePath type is implemented in Rust. This involves
some hackery to allow Rust values to be used directly in C++, via a
helper type whose destructor calls the Rust type's drop()
function. The main issue is the dynamic nature of C++ move semantics:
after we have moved a Rust value, we should not call the drop function
on the original value. So when we move a value, we set the original
value to bitwise zero, and the destructor only calls drop() if the
value is not bitwise zero. This should be sufficient for most types.

Also lots of minor cleanups to the C++ API to make it more modern
(e.g. using std::optional and std::string_view in some places).

Move structured attrs handling into a separate class
This is primarily because Derivation::{can,will}BuildLocally() depends
on attributes like preferLocalBuild and requiredSystemFeatures, but it
can't handle them properly because it doesn't have access to the
structured attributes.
