Remove synchronous API

Part of the fix for #1472

* Remove synchronous API methods
* Update all usages of `CreateConnection` to use `CreateConnectionAsync`
* Ensure that all connections and channels are closed prior to `Dispose`
* Use lowest feasible `LangVersion` for projects
* Add note about nullable reference types in `RabbitMQ.Client.csproj`
* Convert `ManualResetEventSlim` and associated classes to `TaskCompletionSource<bool>` or `SemaphoreSlim`
* Only use `ValueTask` for operations that need the performance benefit
* Add async passive declaration convenience methods to the async API
* Fix missing `CloseAsync` statements prior to disposing `IConnection`
  and `IChannel` instances
* Fix bug where `QueueBindAsync` did not record the binding in an `AutorecoveringChannel`
* Added `ProcessUtil` to run command line executables via `async`
* Make `TopologyRecoveryExceptionHandler` async
* Ensure test classes call `base.DisposeAsync()` appropriately
* Add `RABBITMQ_LONG_RUNNING_TESTS=true` to `build.ps1`
* Remove `Close` and `Abort` from `IConnection` and `IConnectionExtensions`
* Remove `Close` and `Abort` from `IChannel` and `IChannelExtensions`
* Remove use of `RecoveryChannelFactory`
* Remove `Close` from `AutorecoveringConnection` and `Connection`
* Ensure `TestConnectionRecoveryWithoutSetup` tests close and dispose of channels correctly
* Remove `ConfirmSelect`
* Remove `ExchangeBind` and `ExchangeBindNoWait`
* Add `noWait` to `ExchangeBindAsync` and `ExchangeDeclareAsync`
* Remove `ExchangeDeclarePassive`
* Fix stack overflow in `ExchangeBindAsync`
* Remove `ExchangeDelete` and `ExchangeDeleteNoWait`
* Remove `BasicGet`
* Remove `BasicNack`
* Change `BasicNackAsync` to return `ValueTask`
* Remove `BasicCancel` and `BasicCancelNoWait`
* Remove `BasicPublish`
* Remove `BasicQos`
* Remove `BasicReject`
* Remove `ExchangeUnbind` and `ExchangeUnbindNoWait`
* Remove `QueueBind`, `QueueBindNoWait`, QueueDeclare`, `QueueDeclareNoWait`, and `QueueDeclarePassive`
* Remove `QueueDelete` and `QueueDeleteNoWait`
* Make `noWait` the last param in the arg list. Default is `false`
* Remove `BasicAck`
* Modify `IBasicConsumer` to make `HandleBasicDeliver` an async method
* Move `passive` to the end of the argument list, just before `noWait`
* Remove `QueuePurge`
* Remove `QueueUnbind`
* Remove `TxSelect`, `TxCommit` and `TxRollback`
* Remove `WaitForConfirms` and `WaitForConfirmsOrDie`
* Remove `BasicConsume`
* Delete code for sync API
* Make `UpdateSecret` async
