This fixes a bug where Process events were being delivered to secondary
listeners when the Private state thread listener was processing the
event. That meant the secondary listener could get an event before the
Primary listener did. That in turn meant the state when the secondary
listener got the event wasn't right yet. Plus it meant that the
secondary listener saw more events than the primary (not all events get
forwarded from the private to the public Process listener.)

This bug became much more evident when we had a stop hook that did some
work, since that delays the Primary listener event delivery. So I also
added a stop-hook to the test, and put a little delay in as well.

There are 3 ways to create an EventDataBytes object: (const char *),
(llvm::StringRef), and (const void *, size_t len). All of these cases
can be handled under `llvm::StringRef`. Additionally, this allows us to
remove the otherwise unused `SetBytes`, `SwapBytes`, and
`SetBytesFromCString` methods.

Before the addition of the process "Shadow Listener" you could only have one
Listener observing the Process Broadcaster.  That was necessary because fetching the
Process event is what switches the public process state, and for the execution
control logic to be manageable you needed to keep other listeners from causing
this to happen before the main process control engine was ready.

Ismail added the notion of a "ShadowListener" - which allowed you ONE
extra process listener.  This patch inverts that setup by designating the
first listener as primary - and giving it priority in fetching events.

In preparation for removing the `#include "llvm/ADT/StringExtras.h"`
from the header to source file of `llvm/Support/Error.h`, first add in
all the missing includes that were previously included transitively
through this header.

This is fixing all files missed in b0abd4893fa1, 39d8e6e22cd1, and
a11efd49266f.

Broadcasters don't need their names in the StringPool. It doesn't
benefit from fast comparisons and doesn't benefit from uniqueness.

There's no reason these strings need to be in the ConstString
StringPool, they're already string literals with static lifetime.

I plan on addressing other similar functions in follow up commits.

Replace default bodies of special member functions with = default;

The C headers are deprecated so as requested in D102845, this is replacing them
all with their (not deprecated) C++ equivalent.

Summary:
LLVM is using its own isPrint/isSpace implementation that doesn't change depending on the current locale. LLDB should do the same
to prevent that internal logic changes depending on the set locale.
