maven plugin should install maven build-package

[vpa1977]

Bug Description

maven plugin does not install maven build-package.
In order to use maven plugin the image should have maven installed already which is inconvenient.
Would it be possible to append

  build-packages:
      - maven
      - openjdk-21-jdk-headless

if the part does not contain 'build-packages'

To Reproduce

1. create a rockcraft application with a maven part.
2. rockcraft pack

part yaml

application:
    plugin: maven
    source: sample
    source-type: local

This is done on purpose; the idea is to give flexibility on the version of maven/jdk that you use for building the project. As you mentioned, the solution in the general case is to include those build-packages.

We should probably change this to behave like the rust plugin - If there's no maven-deps we install the system maven.

Yes, it would be nice.
Also maven depends on default-jre-headless, so we might want to have default-jdk-headless in build-packages too to deploy command line tools.

Alternative is to make this change rockcraft-only
