Adds chrome-inspector tool and Debug Adapter protocol tool for debugging Enso. # Important Notes The chrome devtools seems to be broken (tracked in https://github.com/oracle/graal/issues/7636). Even `graalpy --inspect ...` fails (Chrome devtools freezes after connecting to the server). This PR adds Debug adapter protocol tool for debugging as a workaround for chrome inspector. There is docs in [dap.md](https://github.com/enso-org/enso/pull/8344/files#diff-421574b50574cfe546e86d4b3d32d79b8b2087f2fe204f68e5cf2693af43bbe1)

Debug Adapter Protocol
Debug Adapter Protocol is yet another instrument available for a Truffle language. The DAP is a native protocol for VSCode and as such, works only via VSCode. To start Enso with DAP server waiting for a client to attach, launch enso via:
env JAVA_OPTS='-Dpolyglot.dap' ./built-distribution/enso-engine-*/enso-*/bin/enso --run *.enso
Once DAP server is started and ready for a client to be attached, the following output will be printed:
[Graal DAP] Starting server and listening on /127.0.0.1:4711
There is a
Launch configuration
in the repository in
.vscode/launch.json
with name Debug Adapter Protocol
, you can start debugging via
Run and Debug view
by selecting the Debug adapter protocol
configuration and pressing play:

Note that the port 4711 is the default port for DAP.
