By moving `host` to the config, we can do a lot further cleanups and
dedups. This anticipates a world where we always go `StoreReference` ->
`*StoreConfig` -> `Store*` rather than skipping the middle step too.
Progress on #10766

In particular `local://<path>` and `unix://` (without any path) now
work, and mean the same things as `local` and `daemon`, respectively. We
thus now have the opportunity to desguar `local` and `daemon` early.
This will allow me to make a change to
https://github.com/NixOS/nix/pull/9839 requested during review to
desugar those earlier.

Now that SourcePath uses a SourceAccessor instead of an InputAccessor,
we can use it in function signatures instead of passing a
SourceAccessor and CanonPath separately.
Instead, serialize as NAR and send that over, then rehash sever side.
This is alorithmically simpler, but comes at the cost of a newer
parameter to `Store::addToStoreFromDump`.

This avoids split-on-whitespace errors:
- No more `bash -c` needed
- No more `shellEscape` needed
- `remote-program` ssh store setting also cleanly supports args (e.g.
`nix daemon`)
- `ssh` uses `--` to separate args for SSH from args for the command to
run.
and will help with Hydra dedup.
Some code taken from #6628.

Factor out `ServeProto::BasicClientConnection` for Hydra to share
- `queryValidPaths`: Hydra uses the lock argument differently than Nix,
so we un-hard-code it.
- `buildDerivationRequest`: Just the request half, as Hydra does some
things between requesting and responding.

Instead of having it be the default method in `Store` itself, have it be
the implementation in `DummyStore` and `LegacySSHStore`. Then just the
implementations which fail to provide the method pay the "penalty" of
dealing with the icky `unimplemented` function for non-compliance.
Picks up where #8217. Getting close to no `unsupported` in the `Store`
interface itself!
More progress on issue #5729.
In https://github.com/NixOS/nix/pull/6134#issuecomment-1079199888,
@thuffschmitt proposed exposing `LegacySSHStore` in Nix for
deduplication with Hydra, at least temporarily. I think that is a good
idea.
Note that the diff will look bad unless one ignores whitespace! Also try
this locally:
```shell-session
git diff --ignore-all-space HEAD^:src/libstore/legacy-ssh-store.cc HEAD:src/libstore/legacy-ssh-store.cc
git diff --ignore-all-space HEAD^:src/libstore/legacy-ssh-store.cc HEAD:src/libstore/legacy-ssh-store.hh
```
