Add annotation to define "test group" and its dependencies

[vlsi]

TestNG Version

7.6.1

Expected behavior

It would be nice if there was a way to declare "group" and its dependencies.

For instance, something like

interface TestGroups {
    @TestGroup
    String FIRST = "FIRST";

    @TestGroup(dependsOnGroups = {FIRST})
    String SECOND = "SECOND";
}

class TestA: TestGroups {
    @Test(groups = [FIRST])
    fun `first group`() {
        println("A: first")
    }

    @Test(groups = [SECOND])
    fun `second group`() {
        println("A: second")
    }
}
...

• dependencies between groups would be better described in test group declaration themselves rather than in @BeforeGroups / @AfterGroups.
• the example above uses "implement TestGroup interface" approach so TestNG could scan and infer groups
• It might be useful to have something like @ImportGroups(TestGroups.class) annotation so users don't have to implement the interface and they would still be able to launch individual test from the IDE (TestNG would infer the needed group definitions)

Actual behavior
