cmStringAlgorithms: cmIsSpace, cmTrimWhitespace, cmEscapeQuotes, cmTokenize

This adds the following functions to `cmStringAlgorithms`:

- `cmIsSpace`
- `cmTrimWhitespace` (moved from `cmSystemTools::TrimWhitespace`)
- `cmEscapeQuotes` (moved from `cmSystemTools::EscapeQuotes`)
- `cmTokenize` (moved from `cmSystemTools::tokenize` and adapted to
  accept `cm::string_view`)
