enable tracy subscriber layer on android (bevyengine#21760)

# Objective

I really need tracing on android right now as I'm attempting to profile
bevy running on a quest 3.

## Solution

I saw [this issue](bevyengine#21612)
already opened about it around 2 weeks ago, and I was able to use it to
figure out how to enable tracy to run on android. However I did not
enable it for IOS and made sure to retain the same behavior for other
flags such as chrome style profiling.

## Testing

I've tested that the engine still builds on both windows and to android.
Additionally the flame graph will now show complete frames of info,
instead of one single mono-frame with 4 different render events.

Android also requires: `android.permission.INTERNET` and possibly
`android.permission.NEARBY_WIFI_DEVICES` to be able to host the debug
server.

## Showcase
Tracy running for an apk deployed to a quest 3.
