/**
Copies a buffer to an allocated buffer of a certain pool type.
Allocates the number bytes specified by AllocationSize of a certain pool type, copies
AllocationSize bytes from Buffer to the newly allocated buffer, and returns a pointer to the
allocated buffer. If AllocationSize is 0, then a valid buffer of 0 size is returned. If there
is not enough memory remaining to satisfy the request, then NULL is returned.
If Buffer is NULL, then ASSERT().
If AllocationSize is greater than (MAX_ADDRESS - Buffer + 1), then ASSERT().
@param PoolType The type of pool to allocate.
@param AllocationSize The number of bytes to allocate and zero.
@param Buffer The buffer to copy to the allocated buffer.
@return A pointer to the allocated buffer or NULL if allocation fails.
