Found this while attempting to document //flutter/runtime. The only reason this was public was because of the desire to use make_shared. I want to documentation changes to include no code changes. Hence this separate patch.

This reverts commit 1e89cb54.

Issue 13238: on iOS, force an orientation change when the current orientation is not allowed (#12295)

Embedders may use this to specify a thread whose event loop is managed by them
instead of the engine. In addition, specifying the same task runner for both
the platform and render task runners allows embedders to effectively perform
GPU rendering operations on the platform thread.

To affect this change, the following non breaking changes to the API have been
made:

* The `FlutterCustomTaskRunners` struct now has a new field `render_task_runner`
  for the specification of a custom render task runner.
* The `FlutterTaskRunnerDescription` has a new field `identifier`. Embedders
  must supply a unique identifier for each task runner they specify. In
  addition, when describing multiple task runners that run their tasks on the
  same thread, their identifiers must match.
* The embedder may need to process tasks during `FlutterEngineRun` and
  `FlutterEngineShutdown`. However, the embedder doesn't have the Flutter engine
  handle before `FlutterEngineRun` and is supposed to relinquish handle right
  before `FlutterEngineShutdown`. Since the embedder needs the Flutter engine
  handle to service tasks on other threads while these calls are underway,
  there exist opportunities for deadlock. To work around this scenario, three
  new calls have been added that allow more deliberate management of the Flutter
  engine instance.
  * `FlutterEngineRun` can be replaced with `FlutterEngineInitialize` and
    `FlutterEngineRunInitialized`. The embedder can obtain a handle to the
    engine after the first call but the engine will not post any tasks to custom
    task runners specified by the embedder till the
    `FlutterEngineRunInitialized` call. Embedders can guard the Flutter engine
    handle behind a mutex for safe task runner interop.
  * `FlutterEngineShutdown` can be preceded by the `FlutterEngineDeinitialize`
    call. After this call the Flutter engine will no longer post tasks onto
    embedder managed task runners. It is still embedder responsibility to
    collect the Flutter engine handle via `FlutterEngineShutdown`.
* To maintain backwards compatibility with the old APIs, `FlutterEngineRun` is
  now just a convenience for `FlutterEngineInitialize` and
  `FlutterEngineRunInitilaized`. `FlutterEngineShutdown` now implicitly calls
  `FlutterEngineDeinitialize` as well. This allows existing users who don't care
  are custom task runner interop to keep using the old APIs.
* Adds complete test coverage for both old and new paths.

The current version is 62.1, which is a now 3 major releases behind,
given that ICU 65 was released on Oct 3, 2019.

The version bump required an update to buildroot to fix too strict compilation
of ICU.

Previous update was here:
https://github.com/flutter/engine/pull/6097

I was advised to upgrade in the code review for this PR:
https://github.com/flutter/engine/pull/13045

This change brings in the function `icu::Locale::forLanguageTag(...)`
which is directly relevant to the work in the PR, but also updates
the library considerably.

Tested:

```bash

set -x

readonly FLUTTER_ENGINE_DIR="${FLUTTER_ENGINE_DIR:-$HOME/fx/flutter/engine/src}"
readonly OUT_DIR="${FLUTTER_ENGINE_DIR}/out"

(
  cd ${FLUTTER_ENGINE_DIR}

  ./flutter/tools/gn --unoptimized
  ninja -j 100 -C "${OUT_DIR}/host_debug_unopt"
  ./flutter/testing/run_tests.py --type engine
)
```

* Support empty strings and vectors in standard codec

Fixes #41993

Currently an empty string or vector will call through to WriteBytes
which asserts that the number of bytes it is being asked to write is
strictly positive. Instead we should not call WriteBytes if the length
is zero.

Similarly, when we read, we don't need to call out if the length is
zero.

* fix typo in test name

* remove unnecessary length check in ReadValue for List

* we also don't need this check before calling read as memcpy can handle size 0
