Adds some entry-level and developer-friendly docs for the debug adapter.
The one in `docs/dap.md` is meant for someone trying to use the debugger
while the one in `docs/reference/buildx_dap_build.md` is more focused on
documenting the command to be integrated in a debugger extension.

Supports using the `evaluate` request in REPL mode to start a container
with the `exec` command. Presently doesn't support any arguments.
This improves the dap server so it is capable of sending reverse
requests and receiving the response. It also adds a hidden command
`dap attach` that attaches to the socket created by `evaluate`.
This requires the client to support `runInTerminal`.
Likely needs some additional work to make sure resources are cleaned up
cleanly especially when the build is unpaused or terminated, but it
should work as a decent base.

This will configure the default behavior when beginning to evaluate a
build target. When `stopOnEntry` is used, it will default to `stepNext`.
Otherwise, `stepContinue` will be used.

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.
