* Don't generate plugin registry in ResidentWebRunner

generateDartPluginRegistry was being set to true unconditionally in
ResidentRunner, bypassing the primary check in
DartPluginRegistrantTarget, and the targetPlatform was not set in that
codepath, bypassing the second after the changes in
https://github.com/flutter/flutter/pull/87991. This caused web hot
restarts to be slower due to doing unnecessary work.

This ensures that generateDartPluginRegistry is false in the
ResidentWebRunner to skip that unnecessary step.

Fixes https://github.com/flutter/flutter/issues/91262

* Flutter_tools for web platform: report error messages with stacks on toolExit

Print error messages and stacks in verbose mode before calling
`throwToolExit` on communication errors to chrome and dwds.

This will help us disagnose CI flakes:

Helps: https://github.com/flutter/flutter/issues/84012
Closes: https://github.com/flutter/flutter/issues/87149

* Added tests

* Extend timeout for testing failure to connect to chrome

* Update rest of chrome tests to await until matching is finished

Also, refactor internal code to do the same.

In principle this is backwards compatible; I just merged all the classes into one and deprecated everything that became redundant as a result.
