Support Gradle build server

[Tomasz Godzik]

Is your feature request related to a problem? Please describe.

It's still early days but I think it's worth to track it. Gradle is starting to support the BSP protocol. It's currently only done in a VS Code plugin, but we might be able to use that at some point.

Sources for it are here https://github.com/microsoft/vscode-gradle/blob/develop/extension/jdtls.ext/com.microsoft.gradle.bs.importer/src/com/microsoft/gradle/bs/importer/GradleBuildServerBuildSupport.java

I managed to work around no existing tooling by creating a json (had some help there):

{
  "name": "gradle",
  "languages": ["java"],
  "argv": [
    "/usr/lib/jvm/openjdk17/bin/java",
    "--add-opens=java.base/java.lang=ALL-UNNAMED",
    "--add-opens=java.base/java.io=ALL-UNNAMED",
    "--add-opens=java.base/java.util=ALL-UNNAMED",
    "-Dplugin.dir=/home/tgodzik/.vscode/extensions/vscjava.vscode-gradle-3.13.3/server/plugins/",
    "-cp",
    "/home/tgodzik/.vscode/extensions/vscjava.vscode-gradle-3.13.3/server/server.jar:/home/tgodzik/.vscode/extensions/vscjava.vscode-gradle-3.13.3/server/runtime/*",
    "com.microsoft.java.bs.core.Launcher"
  ]
}

We would need to download the jars automatically.

Describe the solution you'd like

Some support for Gradle BSP once it's mature enough or if we want we can help out with some stuff that we need.

Describe alternatives you've considered

Use Bloop as we do currently.
