The Azure bot detection can take up to a second to determine if a client is/isn't a bot. To prevent this from slowing down all flutter commands, we can cache the results in the persistent tool state - since we don't expect the same client id to ever become a bot or stop being a bot

[flutter_tool] Refactor Logger and Terminal to (mostly) no longer depend directly on context (#47269)

* Update project.pbxproj files to say Flutter rather than Chromium

Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.

* Update the copyright notice checker to require a standard notice on all files

* Update copyrights on Dart files. (This was a mechanical commit.)

* Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.

Some were already marked "The Flutter Authors", not clear why. Their
dates have been normalized. Some were missing the blank line after the
license. Some were randomly different in trivial ways for no apparent
reason (e.g. missing the trailing period).

* Clean up the copyrights in non-Dart files. (Manual edits.)

Also, make sure templates don't have copyrights.

* Fix some more ORGANIZATIONNAMEs

* On flutter tool crash suggest GitHub template

* Shorten GitHub URLs

* Whitespace

* Wording tweak from @InMatrix

* Review edits

Slight cleanup of file locations in flutter_tools
to make it easier to see which files are responsible
for data reporting.

* Report async callback errors that currently go unreported.
* Add a test

* don't send crash reports if on a user branch.
* add test to test/crash_reporting_test.dart

* add trailing commas on list/map/parameters

* add trailing commas on Invocation with nb of arg>1

* add commas for widget containing widgets

* add trailing commas if instantiation contains trailing comma

* revert bad change

This adds support to AnsiTerminal for colored output, and makes all tool output written to stderr (with the printError function) colored red.

No color codes are sent if the terminal doesn't support color (or isn't a terminal).

Also makes "progress" output print the elapsed time when not connected to a terminal, so that redirected output and terminal output match (redirected output doesn't print the spinner, however).
