cmDocumentationEntry: Drop all user provided ctors for C++ >= 14

There is no need for them cuz:

- the last field has a default value
- all static instances use 2 arguments convertible to `std::string`
- "dynamic" instances used for _Generator_ doc entries access
  fields diectly using default constructed instance

Moreover, compiler may generate move ctor/assign when needed.
