Fix CharacterClass.newlineSequence such that it doesn't crash, CharacterClass.any such that it matches newlines, and implement CharacterClass.anyNonNewline.

Also fix Anchor.startOfLine and Anchor.endOfLine such that they always match newlines.

Map to `.newlineSequence` instead of `.newline`,
which allows it to create the correct consumer.

rdar://96330096
Explicitly disambiguate the fact we're talking
about `.`, which does not match newlines unless in
single line mode.
This time as a "true any" that matches any
character, including newlines.
This should map to `.any`, not `.dot`.

rdar://96509234
This enum will start including cases that only the
DSL can use, so move it off the AST.
Introduce `startOfInput` and `endOfInput` assertion
kinds, and map the DSL to them such that they do
not depend on matching options.
