[native_dio_adapter] Support cronet_http_embedded

[vanyasem]

Request Statement

cronet_http depends on Google Play Services

There is a separate package called cronet_http_embedded which has no such dependency, but is bigger in size

Solution Brainstorm

I'd like to propose creating a separate package native_dio_adapter_embedded that would depend on cronet_http_embedded instead of cronet_http. We have to support devices that do not have Google Play Services installed.

Although I wrote the tool to create the cronet_http_embedded package, I don't think we have a proper way to handle this until Dart team can make its publishing automatic, which can at least avoid the version difference between them.

@AlexV525 thank you for your valuable input! I guess it makes sense to postpone my suggestion until the publishing is made automatic

Cronet embedded is now integrated in the cronet lib. I'm closing this since there's no longer any action needed for this library.
