Return owned `String`s for onion message message types

Returning a reference from a trait method is relatively difficult
to map in bindings and is currently handled by storing the object
in the trait instance, returning a reference to the local field.

This is fine when the object we're returning only needs to live as
long as the trait, but when it needs to be `'static` (as is the
case for onion message `msg_type`s), there's not really a good way
to map them at all.

Instead, here, condition on `#[cfg(c_bindings)]` we return a fully
owned `String`. This is obviously relatively less effecient, but
the extra allocation and `memcpy` isn't the end of the world,
especially given it should be released relatively quickly.

Note that this breaks doctests in with `c_bindings`.

Add a `MessageSendInstructions::ForReply`

Remove message type bound on `ResponseInstruction`

Our onion message handlers generally have one or more methods which
return a `ResponseInstruction` parameterized with the expected
message type (enum) of the message handler.

Sadly, that restriction is impossible to represent in our bindings -
our bindings concretize all LDK structs, enums, and traits into a
single concrete instance with generics set to our concrete trait
instances (which hold a jump table). This prevents us from having
multiple instances of `ResponseInstruction` structs for different
message types.

Our bindings do, however, support different parameterizations of
standard enums, including `Option`s and tuples.

In order to support bindings for the onion message handlers, we
are thus forced into std types bound by expected message types,

instructions and generally using it as a two-tuple of
`(message, ResponseInstruction)`.

Ensure we always pass a `path` for in-workspace dependencies

In order to ensure our crates depend on the workspace copies of
each other in test builds we need to override the crates.io
dependency with a local `path`.

We can do this in one of two ways - either specify the `path` in
the dependency listing in each crate's `Cargo.toml` or use the
workspace `Cargo.toml` to `patch` all dependencies. The first is
tedious while the second lets us have it all in one place. However,
the second option does break `cargo *` in individual crate
directories (forcing the use of `cargo -p crate *` instead) and
makes it rather difficult to depend on local versions of workspace
crates.

Thus, here we drop the `patch.crates-io` from our top-level
`Cargo.toml` entirely.

Still, we do update the `ci/ci-tests.sh` script here to use
`cargo -p crate` instead of switching to each crate's directory as
it allows `cargo` to use a shared `target` and may speed up tests.

Tweak alignment and memory order in the `ProbabilisticScorer`

During routing, the majority of our time is spent in the scorer.
Given the scorer isn't actually doing all that much computation,
this means we're quite sensitive to memory latency. Thus, the cache
lines our data sits on is incredibly important.

Here, we manually lay out the `ChannelLiquidity` and

non-historical scoring and skip historical scoring for channels
with insufficient data by just looking at the same cache line the
channel's SCID is on.

Sadly, to do the full historical scoring we need to load a second
128-byte cache line pair, but we have some time to get there. We
might consider issuing a preload instruction in the future.
