Allow to pass additional modules via common config

[barmac]

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

Because I cannot pass additional module via common config now, I have to know upfront the names of all of the viewers to correctly configure a multi-viewer module, e.g.

      modeler = new Modeler({
        container: container,
        common: {
          executionPlatform: {
            name: 'Camunda Platform',
            version: '7.16.0'
          }
        },
        drd: {
          additionalModules: [
            ExecutionPlatformModule
          ]
        },
        decisionTable: {
          additionalModules: [
            ExecutionPlatformModule
          ]
        },
        literalExpression: {
          additionalModules: [
            ExecutionPlatformModule
          ]
        },
        moddleExtensions: {
          modeler: ModelerModdleExtension
        }
      });

Describe the solution you'd like

Allow to pass additional modules via common.additionalModules:

      modeler = new Modeler({
        container: container,
        common: {
          additionalModules: [
            ExecutionPlatformModule
          ],
          executionPlatform: {
            name: 'Camunda Platform',
            version: '7.16.0'
          }
        },
        moddleExtensions: {
          modeler: ModelerModdleExtension
        }
      });

The common modules should be passed to the injector before the viewer's modules so that they can be overriden.
