optionally return string_view from coerceToString
...
we'll retain the old coerceToString interface that returns a string, but callers
that don't need the returned value to outlive the Value it came from can save
copies by using the new interface instead. for values that weren't stringy we'll
pass a new buffer argument that'll be used for storage and shouldn't be
inspected.

forceValue: make pos mandatory
...
- Make passing the position to `forceValue` mandatory,
this way we remember people that the position is
important for better error messages
- Add pos to all `forceValue` calls

toJSON: report error position for fancier output
...
Given flake:
```nix
{ description = "nix json error provenance";
inputs = {};
outputs = { self }: {
jsonFunction = _: "function";
json = builtins.toJSON (_: "function");
};
}
```
- Before:
```console
❯ nix eval --json .#jsonFunction
error: cannot convert a function to JSON
```
- After:
```console
❯ nix eval --json .#jsonFunction
error: cannot convert a function to JSON
at /nix/store/b7imf1c2j4jnkg3ys7fsfbj02s5j0i4f-source/testflake/flake.nix:4:5:
3| outputs = { self }: {
4| jsonFunction = _: "function";
| ^
5| json = builtins.toJSON (_: "function");

nix eval: Add option to write a directory
...
This is useful for generating the nix manpages, but it may have other
applications (like generating configuration files without a Nix store).

Remove static variable name clashes

This was useful for an experiment with building Nix as a single
compilation unit. It's not very useful otherwise but also doesn't
hurt...

nix: Add --expr flag
...
This replaces the '(...)' installable syntax, which is not very
discoverable. The downside is that you can't have multiple expressions
or mix expressions and other installables.
