* Add DDS ipv6 support

* Use --dds-port for DDS instead of hijacking --host-vmservice-port

Almost all of the flag setup on Linux, macOS, and Windows should be
identical; this pulls that common setup to a shared method.

This adds support for several flags on macOS that have all the necessary
plumbing already in place due to shared backend code, but were never
enabled.

* Reland "Re-enable the Dart Development Service (DDS) (#64671)"

This reverts commit 2ae25cc2.

* Fix MDNS building Observatory URI with port 0 instead of forwarding the device port

* Added MDNS test

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.

[flutter_tools] support code size tooling on iOS, linux, windows, macOS, and Android on Windows (#63610)

Adds support for size analysis on iOS, macOS, linux, and Windows - using an uncompressed directory based approach. The output format is not currently specified.

Adds support for size analysis on android on windows, switching to package:archive

Updates the console format to display as a tree, allowing longer paths. Increases the number of dart libraries shown (to avoid only ever printing the flutter/dart:ui libraries, which dominate the size)

This reverts commit adc9dde3.

- Fixed issue where `FallbackDiscovery` would hold on to a `VmService` when launching on iOS devices, causing DDS to fail to start
- Fixed `flutter drive` case where DDS is already running in another flutter_tools instance

Allow configuring the flutter_manifest to support a synthetic package, this is done through flutter: generate: true.

When running pub get, insert a flutter_gen entry into the packages if it does not already exist. This points to .dart_tool/flutter_gen, which can be updated to contain the generated intl sources (But doesn't currently)

Adds an integration test that verifies this code can be run and imported when enabled.

In web debug mode, infer sound null safety by default. When sound null safety is enabled, provide a separate dill and precompiled Dart SDK. Release builds do not need this setting since we run dart2js from source.

Fixes #59873

The global packages path could cause tests to fail when it would be overriden to unexpected (in test setup) values. Remove most usage and make it a configuration on buildInfo, along with most other build information. Cleanup the asset builder to require the .packages path and the resident runners to no longer require it, since they already have the information in build_info.

It needs to stick around for the fuchsia deps we do not control.

Filled #60232 for remaining work.
