The CFEs FormattedMessage always had two getters to get the text inside
one that would supposedly give an ansi formated version of the message
and one that would supposedly give a plaintext formated version of the
message. They both returned the same string, though, which would either
be with ansi escape codes or plain text depending on the environment at
compile time.
This CL fixes that by having both messages, and letting the reporting
(i.e. whenever the message is read) decide which to use. That way we
can - for instance - report errors with color if the terminal supports
it correctly when reusing a dill (and reissuing problems, but where the
terminal support changes) and if printing the problem to an html <pre>
field (like observatory does).
It also cleans up two different implementations of whether we think
the terminal supports colors or not, by deleting one of them.
This is the second try. Patchset #1 is the original.
Patchset #2(and possibly beyond) is the changes.
TEST=Existing test suites.

This CL completes the migration of the first wave of
interdependent libraries in package:kernel, including ast.dart.
In order to ensure non-nullability on AST properties, the Transformer
has been split in 2 variants: Transformer which doesn't support
removal of nodes and RemovingTransformer which supports removal where
allowed by the context using 'removal sentinels'.
Start reviewing Transformer and RemovingTransformer in visitors.dart
since many of the changes are caused by the changes here.
Included in the migration are the mixin_deduplication.dart and
unreachable_code_elimination.dart since these needed porting to
the RemovingTransformer which was aided by opting in the libraries
which only depended on ast.dart.

The front end previously enforced a stricter-than-spec requirement on
conflicting imports on its own code. The check was included of the
kernel snapshot and therefore always enforced, even in published sdks.
The extra check was removed a month ago and now tools/sdks/ have been
updated to use a later version of the sdk, so the unneeded hide
combinators can now be removed from the source code.

Some notes.
1. `Token.next` is `Token?` because there are null(s) for comment tokens.
But I think that it is never `null` in code, because there is at
least EOF token. So, lots of `!` null checks.
2. `Link.tail` is never null when `isNotEmpty`, but the type system
cannot express it. So, some number of `!` null checks.
3. I keep assert(s) for now, and use comment
`// ignore: unnecessary_null_comparison`.
4. I disabled `can_get_rid_of_nnbd_issue_error`, I think it fails
because of changes in `_fe_analyzer_shared` language version.
Smoke test in google3 looks green.

Even when non-nullable is enabled by default, enabling the experiment
explicitly should result in the experiment release version (and not
the experiment enabled version) to be used for opting in.
For this change, the semantics of parseExperimentalFlags was change
to _not_ normalize the flags to a full mapping including default values.
For this reason all uses of such maps are renamed to
'explicitExperimentalFlags'.

This increases our "local" coverage of the constant evaluator.
Run with something like
`pkg/front_end/test/fasta/strong_tester.dart -DupdateExpectations=true -DstressConstantEvaluator=true -DskipVm=true`
there is now almost coverage of everything (or a comment in the code
suggests that the path is probably unreachable).
Note that
`out/ReleaseX64/dart pkg/front_end/test/vm_service_coverage_constant_evaluator.dart pkg/front_end/test/fasta/strong_tester.dart -DupdateExpectations=true -DstressConstantEvaluator=true -DskipVm=true`
has erroneous misses, for instance (but not limited to) asserts.
These are caused by errors in the VM.
A follow-up CL will be created to turn on "stressConstantEvaluator" by
default and print out any sucesses in the expect files.

This CL:
* Changes the events so beginX and endX events always comes in pairs
(though technically not right as some specific events can be beginX
endY --- but in those cases it is at least documented and used in code
that actually tests it).
-> This entails adding some events and converting something from
"beginX" to "handleX" instead.
* Adds a utility that can generate an AST of sorts directly from the
parser via a listener using the begin/end matching (and knowing of the
specific ones that doesn't match directly).
* Adds a test that checks that - at least for all tested (50,000+) files
- the AST actually generate "correctly", i.e. matches up begin/ends
and ends up with a single top entry "CompilationUnit".
* Adds a different visualization to the parser listener events by
displaying the "AST directly from the parser" in a UI that can be
navigated. The visualization may not be the best, but it's certainly
a stepping stone.
