Synchronization on value classes

Hi,
I am Android platform developer and during [JEP-401](https://openjdk.org/jeps/401) work we've found that [`DefaultEglRenderer`](https://github.com/aws/amazon-chime-sdk-android/blob/515dd196dd005cdc4adbf4f17399a1b169f5506e/amazon-chime-sdk/src/main/java/com/amazonaws/services/chime/sdk/meetings/internal/video/gl/DefaultEglRenderer.kt#L26) synchronizes on `aspectRatio` field whose type is `java.lang.Float`.

In a future release that will throw an exception.

Please take a look at that. Either use a dedicated `java.lang.Object` lock or remove synchronization altogether.

Thanks

Start with DefaultEglRenderer.kt at the aspectRatio field and its synchronization around line 26. Check how aspectRatio is accessed and determine whether synchronization should use a dedicated lock or be removed. Done means the renderer no longer synchronizes on the Float value and the project’s Android checks pass.
