It looks like we should keep RUSTFLAGS consistent in CI if possible;
some commands augmented RUSTFLAGS with "-D warnings" which overrode
`.cargo/config.toml`, causing unnecessary rebuilds even for non-bundling
runs. Tl;dr: for the last few days our average CI time spiked
significantly.
There are several solutions:
- We can place `-D warnings` in our `.cargo/config.toml`. That's not a
good solution, because then you wouldn't ever be able to build Zed with
warnings locally. A true PITA!
- We can place another config.toml somewhere in the search path
(https://doc.rust-lang.org/cargo/reference/config.html#hierarchical-structure)
and rely on the merging of properties. That way we can avoid having `-D
warnings` on developer machines while being able to override CI
behaviour at will.
This PR implements the latter approach by creating the new config file
manually. Ideally we should have it a a separate file in repository
that's moved into $HOME/.cargo on each CI run. Maybe we should even
place it somewhere more local to the checked out Zed version, as placing
it in a global spot is kinda bad too - what if we start building
multiple cargo projects on our CI machines?

This PR extracts the `Story` component into a separate `story` crate so
that it can be shared among various crates that define stories.

This PR fixes a panic that occurs when opening the settings in zed2.
We store the `ThemeRegistry` as a global without wrapping it in an
`Arc`, so we need to retrieve it the same way.

This is an exploration of what it would take to remove the `V` generic
from the element type. Answer: less than I expected.
I added a new struct to GPUI2: `CallbackHandle<Event>`, and reworked the
interactivity related APIs to take this type. I also added a
`.callback()` function to `ViewContext` that can construct a
`CallbackHandle` to wrap our current `|&mut View, &Evt, &mut
ViewContext| {...}` based APIs. With these two changes, we can now
capture the context of the callsite of a click handler, allowing us to
capture all relevant types and data _before_ sending them into GPUI.
This lets us achieve a similar programing style to the existing system,
while also letting us remove all of the generics from the entire element
system. For an example of what this looks like in practice, here's a
side by side diff of the test in `interactive.rs` (which compiles and
passes):

Note how the new arrangement of types is more amenable to rust's type
inference, allowing the code to be just as terse as before despite the
extra function call in the middle.
This approach also allows components to provide well typed APIs to
views, without ever knowing that view's type. This PR includes an
example rewrite of the button component in `ui2`, here's what it's
struct could look like now:

However, I have not yet ported the derive macro for Component to this
new structure, as I know @nathansobo is currently reworking that code.
Once that macro has been rewritten, it should be relatively easy to
rewrite the rest of Zed2 with this approach, the only major difference
that I can foresee is that the editor element would need to wrap it's
operations in an update callback. Though I can think of a few ways to
fix this with a new `ViewElement` trait, that does the wrapping for you.
