This reverts commit d7d12412.

This change re-enables DDS and outputs the DDS URI in place of the VM
service URI on the console. If --disable-dds is not provided,
--host-vmservice-port will be used to determine the port for DDS rather
than the host port for the VM service, which will instead be randomly
chosen.

Because the test bed's CPU is too hot.

Bug: https://github.com/flutter/flutter/issues/64723

* [flutter_tools] add analytics to code size, add more testing

* add gradle case

* Update build_macos_test.dart

* move analytics to code size tooling

* Update analyze_size.dart

* fix analysis

Avoid creating AndroidDevice discovery if the SDK cannot be located. Previously the tool would use which/where adb, however this required us to handle the AndroidSdk class being potentially null - which required an additional layer of indirection around all access. Sometimes these were forgotten leading to NPEs.

In general, not much can be done with an Android Device if the actual SDK is not installed.

Revert "Reland: Increase threshold for usage of compute for utf8 decoding on large strings to 50 KB (#64498)" (#64652)

This reverts commit 54e2a0e6.

* Use Pixel4 for better wait times

According to the firebase team, these have lower wait times for tests.

Revert "[flutter_tools] avoid creating Android Devices if AndroidSDK cannot be found (#64524)" (#64602)

This reverts commit 47596c62.

To allow tests to begin migrating to null safety, sound null safety needs to be disabled. Also removes the experiment flag that is unnecessary since the framework is on the SDK allowlist.
