The size of the LTO build of the engine with the dylib compressed is as follows: ```sh $ du -k libFlutter* 5236 libFlutter.dylib.tar.gz 4324 libFlutterSlimpeller.dylib.tar.gz ``` Sizes are in KiB. This represents a binary size reduction of 17.41% of the compressed artifacts. The compression ratios will likely differ based on the compression scheme. Uncompressed, the sizes are: ```sh $ du -k libFlutter* 16920 libFlutter.dylib 14044 libFlutterSlimpeller.dylib ``` This represents a binary size reduction of 16.99% which is in the same ballpark. The really mucky bit was backing out the raster cache and persistent cache. I want to clean that up in a later patch so that those TUs are part of a separate submodule. Opting out of Impeller will lead to a fatal log at startup saying the opt-out is disallowed. Fixes https://github.com/flutter/flutter/issues/126606
