Disabled DefaultPassthroughCommandDecoder flag on Android to follow upstream

[SergeyZhukovsky]

Resolves #1153
Resolves brave/brave-browser#40225

I don't think anyone has a problem device except me currently. I can confirm that I don't see the problem once I disable the flag and that's how it is in Chrome as well. There are also reports from users that disabling it fixes the issue

It could be verified that passthrough feature is disabled from chrome://gpu. Make sure you have Passthrough Command Decoder set to false in Driver Information section there after the variation applies. That flag is enabled by default, we want to disable it.
