Evaluate TestRequestBuilder.CustomFilters also on class, not just on test.

[jan-varecka-signageos-io]

Now TestRequestBuilder.CustomFilters does not evaluate @CustomFilter on test classes, just on tests. It will be great to have evaluation also for classes.

Because of this missing feature, I need to apply my annotation with @CustomFilter to every test method, or I have to configure instrumentation runner in build.gradle.kts (or in my custom runner). All these solutions are kind of painful in large multimodule project.

android {
    defaultConfig {
        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
        testInstrumentationRunnerArguments["filter"] = listOf(
            "mypackage.MyCustomFilter",
        ).joinToString(separator = ",")
    }
}

or

class MyAndroidJUnitRunner : AndroidJUnitRunner() {

    override fun onCreate(arguments: Bundle) {
        arguments.putString("filter", MyCustomFilter::class.java.name)
        super.onCreate(arguments)
    }
}

Can you also add an entry to runner/android_junit_runner/CHANGELOG.md

I'm missing a test case where the annotation is both on the class and on the methods, with different values.

true { true, false, none } --> 2

This test code esentially simulates consumer code. The consumer shouldn't need to override anything but evaluateTest for this PR to work on classes. And they don't, thanks to the changes in CustomFilters.shouldRun above.

This class shouldn't exist. Usages can be replaced by the existing SampleCustomFilter class.

This annotation shouldn't exist, it's essentially the same as SampleCustomAnnotation, just below.
