Address review feedback: update docs and clarify comments for 128-bit support

- Document the new 128-bit UInt/Int limits (and the platform-support
  caveat) in the language reference, and note the unchanged 64-bit limit
  on bits types, including anonymous bits.
- Move the bits-size note out of testdata/int128_sizes.emb into the docs.
- Reword test comments (drop "now"; -(2**120) instead of ambiguous
  -2**120) and use a hex literal in the text-format test so the value is
  easy to relate to the expected shifted constant.
- Explain the LeastWidthInteger rounding-up recursion in a comment and
  make the no-int128 static_assert message say why the width is
  unsupported.
