Fuchsia will soon remove all support for Component Framework version 1
components (recognized by component manifests ending in `.cmx`).
Notably, some of the `flutter` tool commands for Fuchsia devices--
notably, but not limited to, those related to CFv1--are outdated, and
either do not work today or soon won't work.
This PR removes the outdated components and commands, replacing some
with the newer version, or simply removing the non-working features,
in some cases.
Adds a bit more clarifying documentation to the implementation of the
outputFollowsExit case, and adds tests that verify the behaviour of
stderr, stdout of processes launched via FakeProcessManager.
Specifically:
* Verifies that stderr, stdout are not emitted immediately after process
exit if outputFollowsExit is true. They must be emitted at least one
turn through the event loop later.
* Verifies that ProcessResult.stderr, stdout have the type documented
according to the encoding passted to Process.run/runSync:
* List<int> if null is passed as the encoding.
* String (in the default system encoding) if no encoding is specified.
* String (in the specified encoding) if an encoding is specified.

Because this class has some subtle behaviour with regards to control of
exit timing and when and how it streams data to stderr and stdout, it's
worth adding unit tests for this class directly, as well as (in a
followup patch) for FakeProcessManager.

`FakeProcessManager` is a test-oriented implementation of `ProcessManager`
that simulates launching processes and returning `ProcessResult` objects
whose `exitCode`, `stdout`, `stderr` can be used to write platform-portable,
hermetic tests that don't rely on actually launching processes from
executables on disk. Its `run` and `runSync` methods provide asynchronous and
synchronous variants of this functionality.
Previously, the behaviour of `run` and `runSync` were inconsistent with
regards to the treatment of the `stdoutEncoding` (similarly,
`stderrEncoding`) parameters:
`run`:
* if the encoding was null, `ProcessResult.stdout` was returned as a
String in UTF-8 encoding. This was incorrect. The behaviour as
specified in `ProcessResult.stdout` is that in this case, a raw
`List<int>` should be returned.
* If the encoding was unspecified, `ProcessResult.stdout` was returned as
a `String` in the `io.systemEncoding` encoding. This was correct.
* If the encoding was non-null, `ProcessResult.stdout` was returned as a
`String` in the specified encoding. This was correct.
`runSync`:
* if the encoding was null, `ProcessResult.stdout` was returned as a
`List<int>` in UTF-8 encoding. This was incorrect. The behaviour as
specified in `ProcessResult.stdout` is that in this case, a raw
`List<int>` should be returned.
* If the encoding was unspecified, `ProcessResult.stdout` was returned as
`List<int>` in UTF-8 encoding. This was incorrect. The behaviour as
specified in `ProcessResult.stdout` is that in this case, a String a
`String` in the `io.systemEncoding` encoding should be returned.
* if the encoding was non-null, `ProcessResult.stdout` was returned as a
`String` in unknown (but probably UTF-8) encoding. This was incorrect.
The behaviour as specified in `ProcessResult.stdout` is that in this
case, a `String` in the specified encoding should be returned.
`_FakeProcess`, from which we obtain the fake stdout and stderr values now
holds these fields as raw `List<int>` of bytes rather than as `String`s. It
is up to the user to supply values that can be decoded with the encoding
passed to `run`/`runAsync`.
`run` and `runAsync` have been updated to set stdout (likewise, stderr) as
specified in the `ProcessResult` documentation.
This is pre-factoring for #102451, in which the tool throws an exception
when processing the JSON output from stdout of the `vswhere.exe` tool,
whose output was found to include the `U+FFFD` Unicode replacement
character during UTF-8 decoding, which triggers a `toolExit` exception
when decoded using our [Utf8Decoder][decoder] configured with `reportErrors` =
true. Because `FakeProcessManager.runAsync` did not previously invoke
`utf8.decode` on its output (behaviour which differs from the non-fake
implementation), it was impossible to write tests to verify the fix.
