Fix SemanticsNodeInteraction class properties visibility

[aleks-ex]

The SemanticsNodeInteraction class is defined as follows:

class SemanticsNodeInteraction constructor(
    internal val testContext: TestContext,
    internal val useUnmergedTree: Boolean,
    internal val selector: SemanticsSelector
)

The properties testContext, useUnmergedTree, and selector have internal visibility. This restricts access to these properties from external code that utilizes the library. Consequently, it hinders the creation of custom extension functions necessary for certain testing scenarios.

Current testing API doesn't allow to search descendant deeper than 1st generation as SemanticsNodeInteraction has just onChildren() and onChildAt(index: Int) to find it. (commonMain/androidx/compose/ui/test/Selectors.kt)

For instance, the library provides extension functions for working with lists, such as:

/**
 * Returns children of this node.
 */
fun SemanticsNodeInteraction.onChildren(): SemanticsNodeInteractionCollection {
    return SemanticsNodeInteractionCollection(
        testContext,
        useUnmergedTree,
        selector.addSelectionFromSingleNode("children") { it.children }
    )
}

In my framework, I need to create similar extension functions with custom logic of target elements search. However, I am unable to do so because I do not have access to the testContext, useUnmergedTree, and selector properties.

I kindly request to change the visibility of these properties in the SemanticsNodeInteraction class from internal to public.

Hi! The thing is that SemanticsNodeInteraction belongs to a common code shared with Android Jetpack so whatever proposals you have on this API it's better to start here - https://github.com/androidx/androidx
