When `RemoteMediaDataDecoder::Shutdown` is finished it is not necessary to hold a reference of the `self` any more. Keep the `mChild` alive, which is the only one needed to destroy the IPDL. In addition to that, deleting the IPDL and destroying the child will be happening at the task queue similar to what was happening before Bug 1545416.

Instead of deleteing a RefPtr directly copy it in a local variable in order to ensure that the pointer will be alive till the end of the method. In addition to that, on RemoteMediaDataDecpder::Shutdown promise use a reference of the child object instead of the whole `self` object since this is the only one needed. Finally, one style change.

Create a new IPDL message `ShutdownComplete`, direction from parent (RDD) to child (content), to inform the child when the decoder shutdown has been completed. The remote decoder child uses that message to resolve the shutdown promise.

Detect content process that already has connection to the RDD process
and don't attempt to relaunch or needlessly call
RDDProcessManager::CreateContentBridge. Calling CreateContentBridge
unnecessarily causes churn by recreating RemoteDecoderManagerParents.

Shutting down the taskqueue early prevents the decoder's tasks to be queued.
A TaskQueue no longer requires to be explicitly shutdown it will shutdown when ref counter drops to zero.

Start the RDD process earlier by changing RDDProcessHost to pass the necessary command line arguments for enabling the sandbox.
Per lsmp output on 10.14.3, starting the RDD process sandbox removes access to WindowServer, coreservicesd, lsd and distnoted.
Add a pref (defaulting to on) to control enabling starting the RDD process earlier.

- Modify ProcessDecodedData to return a MediaResult.
- RemoteDecoderParent::RecvInput and RemoteDecoderParent::RecvDrain
both use error returned from ProcessDecodedData to call SendError.
- RemoteVideoDecoderParent and RemoteAudioDecoderParent both return
MediaResult with NS_ERROR_OUT_OF_MEMORY if AllocShmem fails in
ProcessDecodedData (or if the returned buffer size is less than
the requested size).

The seccomp-bpf policy is currently just the "common" policy with no
additions (but with the fixes in bug 1511560 to enable shared memory
creation). The file broker policy allows shared memory creation and
nothing else. The namespace setup is the same as for GMP (i.e., as
restrictive as we currently can be).
The sandbox can be turned off for troubleshooting by setting the
environment variable MOZ_DISABLE_RDD_SANDBOX, similarly to the other
process types.
Tested against https://demo.bitmovin.com/public/firefox/av1/ with the
necessary prefs set.

The number of frames is only meaningful with audio as a VideoData always contain a single frame.
So we only have this member in AudioData, which will simplify the logic in a future commit where the number of frames present depends on the trimming filter applied.
