Issue Description:

$ swift
Welcome to Swift version 5.5.1-dev.
Type :help for assistance.
  1> var b = UnsafeMutableRawBufferPointer.allocate(byteCount: 8, alignment: 8)
b: UnsafeMutableRawBufferPointer = 8 values (0x100404080) {
  [0] = 0
  [1] = 0
  [2] = 0
  [3] = 0
  [4] = 0
  [5] = 0
  [6] = 0
  [7] = 0
}
  2> b.withContiguousStorageIfAvailable { $0.count }
$R0: Int? = nil
  3> b.withContiguousMutableStorageIfAvailable { $0.count } 
$R1: Int? = nil
  4>

I'm not sure there's a good reason to not have them.
