Issue Description:

I had to write something today using UnsafeMutableRawBufferPointer and accidentally wrote UnsafeRawMutableBufferPointer (switching the "Raw" and the "Mutable"). The current order makes sense because (Unsafe)MutableRawBufferPointer is more similar to (Unsafe)RawBufferPointer than it is to (Unsafe)MutableBufferPointer, but you have to stop and think about that to be sure. We could make things easier on people by adding an unavailable typealias with a renamed field.

@available(*, unavailable, renamed: "UnsafeMutableRawBufferPointer")
typealias UnsafeRawMutableBufferPointer = UnsafeMutableRawBufferPointer
