Fix the length of the valueHelp on the --sample option for the create command, and turn on wrapping. (#28264)

The wrapping for some commands was never actually turned on, so this turns it on.

Also, it shortens the `valueHelp` for the `--sample` option to be just "id" instead of "the sample ID of the desired sample from the API documentation website (http://docs.flutter.io)", which was causing the line to get far too long.

Fixes #23074

This reverts commit 76061c4f.

This PR aims at several things:

1. Use pub_semver to check a version in pubspec.yaml meets the requirements specified in https://semver.org/.
2. Don't limit build-number/build-name as a fixed format. Instead, validate it according to the target(ios/android).
3. Make sure that build-number/build-name are always validated no matter it's specified by the `flutter command` or version in pubspec.yaml.

Fixes #27589

This reverts commit 98971f3c.

These are essentially self-inflicted race conditions. Instead of timeouts we're going to try a more verbose logging mechanism that points out when things are taking a long time.

* exp flags in flutter

* Fix test failures

Unique patch numbers are mainly useful for canary and A-B testing, but otherwise complicate things and can now be omitted.

* Renamed --save-compilation-trace to flutter run --train.
* Renamed --precompile=<file> to --compilation-trace-file=<file>.
* In dynamic mode, made JIT snapshot the default, instead of kernel file.

This reverts commit 76f70810.

* Remove many timeouts.

* Get the attach tests to pass.

* Apply review comments from Todd

* More review comment fixes

* Put back the extended timeouts here now that I know why we have them...

* Add ipv6 and observatory port support to the attach command.

* Remove whitespace

* Explain why a name change is useful here

* Refactor common flags out into the parent

* Add an additional test case for when observatory port is provided but debug port is not

* Remove whitespace

* Fix flag validation

`FlutterDevice.views` is limited by a filter. Pipe this filter up as an
option for the commands that instantiate `FlutterDevice`s. This is the
first change necessary for the CLI tooling to target specific isolates
(#22009).

More work needs to be done after this patch.
* Isolate names are dynamically generated and change every restart.
* This just filters views, not background isolates (`VMService.isolates`).

This attempts to re-land #22656.

There are two changes from the original:

I turned off wrapping completely when not sending output to a terminal. Previously I had defaulted to wrapping at and arbitrary 100 chars in that case, just to keep long messages from being too long, but that turns out the be a bad idea because there are tests that are relying on the specific form of the output. It's also pretty arbitrary, and mostly people sending output to a non-terminal will want unwrapped text.

I found a better way to terminate ANSI color/bold sequences, so that they can be embedded within each other without needed quite as complex a dance with removing redundant sequences.

As part of these changes, I removed the Logger.supportsColor setter so that the one source of truth for color support is in AnsiTerminal.supportsColor.

*     Turn on line wrapping again in usage and status messages, adds ANSI color to doctor and analysis messages. (#22656)

    This turns on text wrapping for usage messages and status messages. When on a terminal, wraps to the width of the terminal. When writing to a non-terminal, wrap lines at a default column width (currently defined to be 100 chars). If --no-wrap is specified, then no wrapping occurs. If --wrap-column is specified, wraps to that column (if --wrap is on).

    Adds ANSI color to the doctor and analysis output on terminals. This is in this PR with the wrapping, since wrapping needs to know how to count visible characters in the presence of ANSI sequences. (This is just one more step towards re-implementing all of Curses for Flutter. :-)) Will not print ANSI sequences when sent to a non-terminal, or of --no-color is specified.

    Fixes ANSI color and bold sequences so that they can be combined (bold, colored text), and a small bug in indentation calculation for wrapping.

    Since wrapping is now turned on, also removed many redundant '\n's in the code.

Revert "Turn on line wrapping in usage and status messages, adds ANSI color to doctor and analysis messages. (#22656)" (#22759)

This reverts commit e4386321
because it breaks 160 benchmarks, and several devicelab tests,
due to changing the format of the output.
