Summary:
We currently have a single WebAuthnManager instance per process that's shared
between all CredentialContainers. That way the nsPIDOMWindowInner parent has
to be tracked by the transaction, as multiple containers could kick off
requests simultaneously.
This patch lets us we have one WebAuthnManager instance per each
CredentialsContainer and thus each nsPIDOMWindowInner. This matches the current
U2F implementation where there is one instance per parent window too.
This somewhat simplifies the communication diagram (at least in my head), as
each U2F/WebAuthnManager instance also has their own TransactionChild/Parent
pair for IPC protocol communication. The manager and child/parent pair are
destroyed when the window is.

Summary:
This patch fixes the reported leak of U2FTransactionChild instances in the
content process by introducing a WebAuthnTransactionChildBase class that both
WebAuthnTransactionChild and U2FTransactionChild inherit from.
This base class is responsible for proper refcounting. In
BackgroundChildImpl::DeallocPWebAuthnTransactionChild() we currently always
cast to WebAuthnTransactionChild, that will work only for the WebAuthn API. We
can now cast to WebAuthnTransactionChildBase to make this work for U2F as well.

Summary:
We currently call ChildActor.send__delete() when clearing an active transaction
and thereby destroy the child actor. If that happens, e.g. due to a tab switch,
while a message is in the IPC buffer waiting to be delivered, we crash.
This patch creates the child actor lazily as before, but keeps it around until
the WebAuthnManager goes away, which will be at process shutdown.
Each transaction now has a unique id, that the parent process will include in
any of the ConfirmRegister, ConfirmSign, or Abort messages. That way we can
easily ignore stale messages that were in the buffer while we started a new
transaction or cancelled the current one.

Summary:
We currently allow sending a "Cancel" message from the child to abort a running
transaction, e.g. when the user switches away from the currently active tab.
We have a message with the same name "Cancel" sent by the parent when the
transaction is aborted due to failure somewhere in the token manager.
This patch renames abort messages from the parent to "Abort" to clarify the
purpose of the message.

Takes functionality once in the WebAuthentication DOM class that needs
to be handled by the content process, and moves it to a
singleton (per-content-process) manager class. This allows the
WebAuthn API to centralize management of transactions and IPC
channels. Patch also creates the child (content-process) classes for
WebAuthn IPC channels.
