Remove random/internal/distributions.h

This file was something of an historical artifact. All of the related
code has either been removed or migraged, and so the only remaining type
belongs with uniform_helper.h, as it is used to infer the return type
of the absl::Uniform method in a few cases.

Let Cord::Cord(string&&), Cord::operator=(string&&),
Cord::Append(string&&), and Cord::Prepend(string&&) steal string data
and embed it into the Cord as a single external chunk, instead of
copying it into flat chunks (at most 4083-byte each).

Stealing string data is faster, but it creates a long chunk, which leads
to a higher more memory usage if its subcords are created and outlive
the whole Cord.

These functions revert to copying the data if any of the following
conditions holds:
- string size is at most kMaxBytesToCopy (511), to avoid the overhead
  of an external chunk for short strings;
- less than half of string capacity is used, to avoid pinning to much
  unused memory.
