libexpr: Support structured error classes 
While preparing PRs like #9753, I've had to change error messages in
dozens of code paths. It would be nice if instead of

    EvalError("expected 'boolean' but found '%1%'", showType(v))

we could write

    TypeError(v, "boolean")

or similar. Then, changing the error message could be a mechanical
refactor with the compiler pointing out places the constructor needs to
be changed, rather than the error-prone process of grepping through the
codebase. Structured errors would also help prevent the "same" error
from having multiple slightly different messages, and could be a first
step towards error codes / an error index.

This PR reworks the exception infrastructure in `libexpr` to
support exception types with different constructor signatures than
`BaseError`. Actually refactoring the exceptions to use structured data
will come in a future PR (this one is big enough already, as it has to
touch every exception in `libexpr`).

The core design is in `eval-error.hh`. Generally, errors like this:

    state.error("'%s' is not a string", getAttrPathStr())
      .debugThrow<TypeError>()

are transformed like this:

    state.error<TypeError>("'%s' is not a string", getAttrPathStr())
      .debugThrow()

The type annotation has moved from `ErrorBuilder::debugThrow` to
`EvalState::error`.

1ee42c5b88 builtin:fetchurl: Ensure a fixed-output derivation 
Previously we didn't check that the derivation was fixed-output, so
you could use builtin:fetchurl to impurely fetch a file.

f1b4663805 Disallow store path names that are . or .. (plus opt. -) 
As discussed in the maintainer meeting on 2024-01-29.

Mainly this is to avoid a situation where the name is parsed and
treated as a file name, mostly to protect users.
.-* and ..-* are also considered invalid because they might strip
on that separator to remove versions. Doesn't really work, but that's
what we decided, and I won't argue with it, because .-* probably
doesn't seem to have a real world application anyway.
We do still permit a 1-character name that's just "-", which still
poses a similar risk in such a situation. We can't start disallowing
trailing -, because a non-zero number of users will need it and we've
seen how annoying and painful such a change is.

What matters most is preventing a situation where . or .. can be
injected, and to just get this done.

caea7dcb7e Change an allowPath call to take a store path again 
This looks like a revert of #5844, but is not.

That one was needed because
d90f9d4b99 (diff-0f59bb6f197822ef9f19ceae9624989499d170c84dfdc1f486a8959bb4588cafR85)
changed the type of the argument to `allowPath` from a `StorePath` to a
`Path`. But since
caabc4f648 (diff-0f59bb6f197822ef9f19ceae9624989499d170c84dfdc1f486a8959bb4588cafL100-R92),
it is a `StorePath` again.

I think this is worth changing because we want to be very careful about
`toRealPath` and the evaluator --- ideally the choice of real path does
not affect evaluation at all. So using it fewer times is better.

49b25ea85c refactor: Impure derivation type isPure -> isImpure 
To quote the method doc:

Non-impure derivations can still behave impurely, to the degree permitted
by the sandbox. Hence why this method isn't `isPure`: impure derivations
are not the negation of pure derivations. Purity can not be ascertained
except by rather heavy tools.

that is but having the include here is definitely more correct.
