Subject: [PATCH] [string] Consistently spell return types and types of data
 members

Affected sections:
- [basic.string.general] Align both overloads of `data`
- [basic.string.general] Use `(const_)reference` for consistency with
other sequence containers
- [string.access] Use `(const_)reference` for consistency with other
sequence containers
- [string.view.template.general] Use `const charT*` for `data` and a
data member, for the consistency with `basic_string`.
-[string.view.access] Use `const charT*` for `data` for consistency with
`basic_string`
