When flutter/synchronization was first authored, we did not own fml (it was called fxl then). Now we do, so use a single spot for such utilities. The pipeline was meant to be a general purpose utility that was only ever used by the animator (it even has animator specific tracing), so move that to shell instead (where the animator resides).
* Revert "Revert "Guard the service protocol's global handlers list with a reader/writer lock (#6888) #6895" (#6899)"
This reverts commit b6e93759faa92a96650e326b0e82578a6803c46d and applies fix for tests on Windows.
* Reland guard the service protocol's global handlers list with a reader/writer lock.
* Remove blank line
The service protocol holds the lock while waiting for completion of service
RPC tasks. These tasks (specifically hot restart/RunInView) may need to
modify a handler's description data.
Task execution and ServiceProtocol::SetHandlerDescription will obtain a shared
lock to make this possible. AddHandler and RemoveHandler will obtain an
exclusive lock in order to guard against a handler being deleted while a
service task is running.

* Reland "Added IsolateNameServer functionality (#5410)"
This reverts commit c3976b3c7183f479717bffed3f640fb92afbd3dc.
* Fixed issue with isolate_name_server_test which caused test to timeout
* Disabled thread_annotations on Android as they aren't supported in the
NDK headers for std::mutex. Readded thread annotations to
IsolateNameServer.
