Currently, when deserialization fails, the error message contains the base
name of the C++ type, without template parameters; this means we can get
unhelpfully vague errors about `RefPtr` or `Maybe` or `nsTArray`. (The
identical error cases are then merged by the compiler, so the execution
path can't be recovered from the crash dump.)
This patch uses the IPDL type instead. It would be possible to invoke
the code generator to use the full C++ type, but more complicated for no
real benefit.

In sandboxed processes with Win32k lockdown, when we initialize COM using an MTA
on a background thread, the main thread is automatically initialized by the COM
runtime as having an implicit MTA.
This is fine, except for the fact that if we want to enqueue any work that needs
to operate specifically on the EnsureMTA thread, it won't happen.
This patch adds a flag to EnsureMTA's constructor that ensures that, even if the
current thread is in an MTA (implicit or otherwise), we still forcibly enqueue
the closure specifically to the EnsureMTA thread.

FileCreatorHelper creates a FileBlobImpl on the main-thread and, because of
this, we end up executing I/O operations on that thread, slowing down other
components. With this patch, FileCreatorHelper logic is moved to PBackground.
That the 'type' getter is still called on the main-thread because FileBlobImpl
uses nsIMIMEService which is a non thread-safe component.

The maximum size of an IPC message is defined twice; IPC::Channel::kMaximumMessageSize = 256 MiB and IPC::MAX_MESSAGE_SIZE = 65 KiB . The latter one is used for Windows printing and its small size could cause errors.
I removed the small constant, and made changes to the files using it :
- The windows printing file now uses kMaximumMessageSize / 2
- nsWebBrowserPersist uses its old constant

Cmd-line params for the SharedPreferenceSerializer was
duplicated in ContentParent and
SocketProcessHost. Since we'll have a 3rd process (RDD)
using this same code, let's move the repsonsiblity for knowing how to add
these cmdline params into SharedPreferenceSerializer.

The binary path type of a particular content process is useful information
outside of IPC. Given that `XRE_EnableSameExecutableForContentProc` already
exists, and given that the binary path type is closely related to
`GeckoProcessType`, I've added a new function, `XRE_GetContentProcBinPathType`.
The mapping of process type to binary type has been moved to the
`GeckoProcessTypes` definitions.
This patch also modifies `ipc::GeckoChildProcessHost` to call into the new
function.

PPluginInstance's __delete__ was ported from rpc to intr, and is the
only non-async IPDL deletion in the codebase. We should be able to
align this with the rest of the IPDL interfaces and remove the need
for specialized intr __delete__ handling.

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.

Add a new nsExternalHelperAppService derived class named nsOSHelperAppServiceChild to be used for the MIME service, external helper app service, and external protocol service interfaces in child processes. nsOSHelperAppServiceChild overrides some methods used to get MIME and external protocol handler information from the OS and implements these methods by remoting the calls to the parent process.
This is necessary because, on Mac, querying the OS for helper application info from sandboxed content processes is unreliable and has buggy side effects.
For now, only use the new class on Mac.
