This refines the check for determining whether exec will succeed to work
when an error occurs. This check previously relied on the `Ref` being
populated in the result context but this would only happen if we were
paused from a breakpoint or by stepping. An error would not fill in this
field.
The check is now refined to use the new gateway filesystem exec API so
we can create the container and then check even if we don't have a
returned gateway reference. The logic to determine which mount to check
has also been moved.

Invoking the shell will cause it to persist across the entire build and
to re-execute whenever the builder pauses at another location again.
This still requires using `exec` to launch the shell. Launching by frame
id is also removed since it no longer applies to this version.

Adds a simple implementation of the debug adapter that supports the very
basics of a debug adapter.
It supports the launch request, the configuration done request, the
creation of threads, stopping, resuming, and disconnecting from server.
It does not support custom breakpoints, stack traces, or variable
inspection yet. These are planned to be added in the future.

This changes the build handler to customize the behavior of evaluate
rather than onresult and also simplifies the `ResultHandle`. The
`ResultHandle` is now only valid within the gateway callback and can be
used to start containers from the handler.
`Evaluate` now executes inside of the gateway callback rather than
having a separate implementation that executes or re-invokes the build.
This keeps the gateway callback session open until the debugger has
returned.
The `ErrReload` for monitor has now been moved into the `build` package
and been renamed to `ErrRestart`. This is because it restarts the build
so the name makes a bit more sense. The actual use of this functionality
is still tied to the monitor reload.

Removes all references to the controller and moves the remaining
sections of code to other packages.
Processes has been moved to monitor where it is used and the data
structs have been removed so buildflags is used directly. The controller
build function has been moved to the commands package.

Removes gogo/protobuf from buildx and updates to a version of
moby/buildkit where gogo is removed.
This also changes how the proto files are generated. This is because
newer versions of protobuf are more strict about name conflicts. If two
files have the same name (even if they are relative paths) and are used
in different protoc commands, they'll conflict in the registry.
Since protobuf file generation doesn't work very well with
`paths=source_relative`, this removes the `go:generate` expression and
just relies on the dockerfile to perform the generation.

Now, we always perform the full solve request in the main gateway call.
This ensures that progress works properly, and makes the lifetime
semantics much clearer.
NewResultContext abstracts the details of a successful/failed build, to
always return a single ResultContext, even though the details of how a
gateway is created is different:
- For a failed build, we can just keep the gateway open.
- For a successful build, we immediately open another gateway and
re-evaluate the build definition in that gateway. This should give an
instant cache hit (since the build was just successful).
