After https://github.com/JetBrains/skiko/pull/798, we changed Dispatcher.IO to custom dispatcher.

Dispatcher.IO is based on daemon threads (thread that receives InterruptException on application exit).

Our new dispatcher isn't. The proof:
```
import java.util.concurrent.Executors
import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.asCoroutineDispatcher
import kotlinx.coroutines.runBlocking

fun main() {
    runBlocking(Dispatchers.IO) {
        println(Thread.currentThread().isDaemon) // prints true
    }
    runBlocking(Executors.newCachedThreadPool().asCoroutineDispatcher()) {
        println(Thread.currentThread().isDaemon) // prints false
    }
    val defaultFactory = Executors.defaultThreadFactory()
    runBlocking(Executors.newCachedThreadPool {
        defaultFactory.newThread(it).apply {
            isDaemon = true
        }
    }.asCoroutineDispatcher()) {
        println(Thread.currentThread().isDaemon) // prints true
    }
}
```

This PR makes threads daemon.

Reported in [Kotlin Slack](https://kotlinlang.slack.com/archives/C01D6HTPATV/p1697400320739369) - applications exits too long.

Passing null into the "positions" parameter of a gradient shader factory
that accepts a custom ColorSpace caused a segfault prior to this fix.

* Fix crash on Windows machines without OpenGL

Some Windows CI machines don't contain OpenGL, so Skiko/Compose will crash on them. It shouldn't crash, it should fallback to Software rendering

To properly fallback, we need to load opengl32.dll dynamically in runtime.

Fixes https://github.com/JetBrains/compose-multiplatform/issues/3243

# Test 1
- `gradlew publishToMavenLocal` is successful (if we use functions directly, it fails with "error LNK2019: unresolved external symbol")
- `SkiaLayerTest` is successful (it tests OpenGL as well)

# Test 2
1. Remove `C:\Windows\System32\opengl32.dll`
2. `SkiaLayerTest` still should be successful, but logs should contain that it fallbacks to Software rendering.

# Test 3
1. Compile local skiko
2. Run Compose run1 and tests

Workaround was added in this PR: https://github.com/JetBrains/skiko/pull/682

Use workaround with Java sources. Because a platform Java type can be used as a platform type MotionEvent!

Rename interface to SkikoUITextInputTraits
Also added missing functions from https://developer.apple.com/documentation/uikit/uitextinputtraits?language=objc
