6a8de4c9dc Avoid enumerating entire overlay store dir upfront.
As an optimisation for LocalStore, we read all the store directory entries into
a set. Checking for membership of this set is much faster than a stat syscall.
However for LocalOverlayStore, the lower store directory is expected to contain
a vast number of entries and reading them all can take a very long time.

So instead of enumerating them all upfront, we call pathExists as needed. This
means making stat syscalls for each store path, but the upper layer is expected
to be relatively small compared to the lower store so that should be okay.

6525265f46 LocalStore::verifyPath: Try to clarify data flow with more scopes
It was initially unclear to me which of these are temporary state for
the verify paths computation, and which of these are the results of that
computation to be used in the rest of the function. Now, it is clear,
and enforced.

2a5f5fbb17 LocalStore::verifyPath: Use StorePathSet for store local var
We don't care about non-store-paths in there (things like `.links`, are,
in fact, allowed). So let's just skip them up front and be more strongly
typed.

c9a87ce7ca Refactor verifyPath to take StorePath instead of Path.
This way we avoid having to convert from Path to StorePath and vice versa in
the body of verifyPath.

Add parseFlakeRef and flakeRefToString builtins (#8670)
Over the last year or so I've run into several use cases where I need to
parse and/or serialize URLs for use by `builtins.fetchTree` or
`builtins.getFlake`, largely in order to produce _lockfile-like_ files
for lang2nix frameworks or tools which use `nix` internally to drive
builds.

I've gone through the painstaking process of emulating
`nix::FlakeRef::fromAttrs` and `nix::parseFlakeRef` several times with
mixed success; but these are difficult to create and even harder to
maintain if I hope to stay aligned with changes to the real
parser/serializer.

I understand why adding new `builtins` isn't something we want to do
flagrantly. I'm recommending this addition simply because I keep
encountering use cases where I need to parse/serialize these URIs in
`nix` expressions, and I want a reliable solution.
