Support scrollbars for text fields

[igordmn]

0.4.0-build211

Currently there is no way to add scrollbars to the text field because text fields have their own scroll state that is not accessible outside of the text field.

import androidx.compose.desktop.Window
import androidx.compose.foundation.VerticalScrollbar
import androidx.compose.foundation.layout.Box
import androidx.compose.foundation.layout.fillMaxHeight
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.foundation.rememberScrollState
import androidx.compose.foundation.rememberScrollbarAdapter
import androidx.compose.foundation.text.BasicTextField
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier

fun main() = Window {
    val scrollState = rememberScrollState()
    Box(
        modifier = Modifier.fillMaxSize()
    ) {
        BasicTextField((1..10000).joinToString { "x" }, {}, Modifier.fillMaxSize())
        VerticalScrollbar(
            rememberScrollbarAdapter(scrollState),
            modifier = Modifier.align(Alignment.CenterEnd).fillMaxHeight()
        )
    }
}
