Android-Gui: Allow setting the DecorView to transparent color

[fritsch]

Sony TVs have a long standing firmware bug. Allow a user to configure the background color to workaround this.

Usage:

<advancedsettings>
  <gui>
   <transparentguilayout>true</transparentguilayout>
 </gui>
</advancedsettings>

First draf for #25166 - I only wrote the code. I did neither compile nor runtime test it. Also did not verify the thingy we want to alter is already there. Just that we have discussion starting point.

This is a one time setting. While it uses quietvoid's code from back then - it is not dolby vision depending but applies globally as the Sony People have GUI issues in general. Could be combined with other regressions more dynamically.

I have an Android TV SONY KD-55XE9005 that is about 6/7 years old and since the Kodi update 21 I have gray transparent bars in films where the black bars were removed when playing, it looks terrible. Do you have any instructions for me on how I can remove this so that the bars are black again? Thanks for your help!

Best regards

Hi @fritsch, this is working for me on FireTV stick: quietvoid@5d6b162

The DecorView in the past was transparent. Now I'm not sure what it is by default but the color is not set by Kodi anymore.
But the VideoLayout view is the one that needs to be changed by the advanced setting, at least on my device.

I'm not sure what the view hierarchy is, but hopefully changing only VideoLayout is good enough.

@quietvoid Cool! Feel free to replace this PR. Thanks very much.
