Adds some more helpers for parsing database values.

The queries would not be interpolated anymore, because we didn’t pass
the thing down deep enough.
Also only init the `pgFormatPool` if we want to use the formatter,
this saves on a bunch of subprocesses.

It turns out the pg_format thing is just too slow for my use-cases
most of the time, even when pooling the mf. Most queries stay 90%+ in
the perl script, even though they are very fast to execute on their
own, screwing up the traces a lot.
So instead I replace the `postgres-simple` quasi-quoter that strips
whitespace (and tends to screw up queries anyway) with a simple one
that just removes the outer indentation up to the first line.
Why did I spend so much time on pg_format haha

Default to always leaking strings, and copying strings by copying
pointers rather than cloning the underlying allocation. This (somewhat
bafflingly) doesn't seem to affect any benchmarks, but paves the way for
some tricks around string allocation that do.
Unfortunately, we can't do this (yet?) for contextful strings, for
reasons I don't currently understand but which I will address later,
when I address contextful strings more holistically.
I've left a flag in here to disable this, both to test the cloning logic
for strings for when/if we decide to bring this back, and to allow
people who care more about memory usage than perf to disable leaking.

The "path" key in the arguments to builtins.path supports any
path-coercible type (a string, a path...). Coerce it to a path in the
argument rather than just requiring it already be one and throwing an
error if it's not.
This is... annoying to test, since it requires a file with known
contents that's available in the build sandbox. But it works! Trust me!

We use a trick where buttons are nested into a form element, passing

`hx-vals`. If htmx is disabled, just redirect and reload the full page

Previously, OpConstant would display some detail about its
ConstantIdx: whether it's a thunk or closure, and what its address
is. This has been expanded to also show when the ConstantIdx is a
blueprint, along with the blueprint's address, and to the other
opcodes that use a ConstantIdx.
Currently, it seems like blueprint addresses don't correspond to the
address of the thunk listed in the bytecode output, but it's still
useful to see that the constant being grabbed is a blueprint, and
maybe this pointer can be made to make more sense in the future.

path_exists was returning an error when certain common IO errors were
encountered. e.g. in the path "/dev/null/.", path_exists would throw
an error because the underlying call to Path::try_exists threw an
error because null isn't a directory. But if null isn't a directory,
then the path is invalid, so this should really be returning
false. That's what nix's behavior is and that's what makes sense.
The trait function isn't being changed because some other
implementers (e.g. tvix_store_io) have actual errors they can throw.

- The deduplicated directory is obtained removed from expected_directory_digests
- The second reference to the deduplicated directory is added to expected_directory_digests
- The deduplicated directory has already been sent, but is still in the
expected_directory_digests. It looks to the GRPC client like the
closure is incomplete and the stream ended prematurely.
