TBR=csmartdalton@google.com

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

dart-lang/sdk@fc933312f7 [vm] Allow inlining of force optimized functions in AoT
dart-lang/sdk@ba9d61ac96 [vm] Allow unaligned accesses by default in SIMARM64

This Pull Request simple adds the deviceId property to the encoding method, I am preparing a next PR on the flutter repository that reads this info and add a property to RawKeyEventDataAndroid on the Flutter side.

This is necessary so we can support multiple gamepads on Android, in order to be possible to make a local multiplayer game with Flutter.

* refactoring before implementing the firefox installer. This PR carries utilities to a common place. Renames the lock file with a generic name.

* Fixed README file for browser_lock

* addressing PR comments: removing unimplemented firefox methods.

Fixes a bug where `PlatformViewController` was not being notified of `FlutterView` attachment changes.

* Implement basic drawVertices for BlendMode.srcOver and hairline rendering
* Implement maxDiffRate parameter for screenshot tests

So it's the same with the GPU thread.

Otherwise, some shaders may be cached in binary on the IO thread, and we will lose them when we do the SkSL precompile.
