This change refactors the DAP `Event` type, the `helix_dap` module and
the `helix_dap::transport` module to be closer to the equivalent
implementations in `helix_lsp`. The DAP `Event` type is similar to LSP's
`Notification` so this change rewrites the enum as a trait which is
implemented by empty types (for example `enum Initialized {}`).
`Event` is then reintroduced as an enum in `helix_dap` with a helper
function to convert from the `Event` as the transport knows it. By
separating the definitions of `Event` between lib and transport, we can
handle incoming events which are not known to our `Event` enum. For
example debugpy sends `"debugpySockets"` which is unknown. With this
change, unknown events are discarded with an info-level log message.
The `Request` type was already a trait but did not have an enum with the
known values. This change also introduces a `helix_dap::Request` enum
similar to `helix_dap::Event`. This resolves a TODO comment about
avoiding `unwrap` when parsing the request's arguments.

Send a `Disconnect` DAP request if the `Terminated` event is received.
According to the specification, if the debugging session was started by
as `launch`, the debuggee should be terminated alongside the session. If
instead the session was started as `attach`, it should not be disposed of.
This default behaviour can be overriden if the `supportTerminateDebuggee`
capability is supported by the adapter, through the `Disconnect` request
`terminateDebuggee` argument, as described in
[the specification][discon-spec].
This also implies saving the starting command for a debug sessions, in
order to decide which behaviour should be used, as well as validating the
capabilities of the adapter, in order to decide what the disconnect should
do.
An additional change made is handling of the `Exited` event, showing a
message if the exit code is different than `0`, for the user to be aware
off the termination failure.

This line uses the Display trait for io::ErrorKind which was
stabilized in Rust 1.60.0. We can set MSRV all the way back to
1.57.0 by replacing it with a pretty-print.
Closes#2460.
