Add support for per-prefix transmission throttling

In patch 4.4.0 and 10.2.7 Blizzard have tightened the restrictions on
addon comms to add a per-prefix throttle across all chat types,
effectively restricting them to one message per second with a small
accrued burst capacity.

The SendAddonMessage APIs now return an enum result code which includes
information if this client-side throttle has been applied to a submitted
message. With it, we can now properly handle throttling in CTL and
avoid situations where addon messages would be dropped for exceeding it.

This PR takes into consideration the discussion on Discord and takes a
slightly different approach to the other open one by instead
implementing the concept of a "blocked" pipe.

A pipe enters the "blocked" state whenever a message at its head is
attempted to be sent off, and a throttle result code is returned from
the API.

When transitioning to this state, the pipe is removed from the
transmission ring of its parent priority and is instead placed into a
separate (and new) blocked ring. This prevents the despool logic from
seeing blocked pipes and pointlessly attempting to re-send on them.

Periodically - currently every 0.35s - the contents of the blocked
rings in each priority are reintegrated back into the transmission
rings, allowing us to attempt re-transmission of queued messages.

This means there may be some added latency when a prefix entered a
blocked state if the API was about to perhaps unblock it, but this
also allows us to reallocate bandwidth that would be consumed by
priorities that are fully blocked to others that can more readily
use it. The value of 0.35s was chosen almost arbitrarily and could
be tuned later if found to be a bit high.

It's important to also note that we specifically don't consider the
'ChannelThrottle' return code a retryable error condition. The reasoning
here is that this throttle isn't new, and the API can return this value
but still sometimes send off the message albeit subject to additional
server-side throttling checks - and also at the time of writing, a
server-side bug that causes it to more aggressively throttle than
it actually should.

Aside from prefix throttling, there's a few other small changes.

- Failure to send a message either due to an error or throttling no
  longer consumes bandwidth that had been allocated to a priority.

- Priorities that enter a blocked or empty state now release their
  bandwidth back to the global pool for redistribution immediately,
  instead of waiting until there's no data queued up whatsoever. This
  is required to deal with edge cases involving priorities sending
  many small messages on one prefix infinitely accumulating bandwidth.

- Transmission logic has been centralized into a new PerformSend
  function to minimize the number of call sites individually needing
  to remember to toggle boolean variables with each Send call.

- Queued transmissions no longer apply checks to see if the player
  is in a group or raid. The API has dedicated return codes for this
  condition and has been tested to not trigger erroneous system
  message spam if attempting to send a message to either chat type
  while not being in a group. This is not the case for guilds, however
  the library never checked this case previously so one hasn't been
  added.

- User-supplied callbacks are now supplied an accurate 'didSend'
  parameter that will be false if the API returns a non-throttle-related
  error code.

- User-supplied callbacks are additionally now supplied the new result
  code as a third parameter. For Classic Era, we synthesize one from a
  subset of the enum values based off the boolean result that the API
  will still be providing there for now.

- User-supplied callbacks no longer let errors blow things up in an
  uncontrolled manner by being subject to securecall wrapping. This
  is also consistently applied irrespective of whether or not the
  send itself was immediate or queued.

- Some compatibility with the pre-8.0 global SendAddonMessage API was
  removed as it's no longer needed.
