Use in API and utilities WKT2_2019 instead of WKT2_2018 (fixes #1518)

- C API: PJ_GUESSED_WKT2_2019 is added, PJ_GUESSED_WKT2_2018 aliased to it
- C API: PJ_WKT2_2019[_SIMPLIFIED] is added, PJ_WKT2_2018[_SIMPLIFIED] alias to it
- C++ API: similarly for WKTFormatter::Convention::WKT2_2019[_SIMPLIFIED]
Those above changes should be fully backward API and ABI compatible.

projinfo changes:
- accept WKT2_2019 as value for -o switch. WKT2_2018 is still accepted (undocumented)
- output now uses 'WKT2_2019 string:', so might break scripts that would rely on that.

Other internal code references to WKT2_2018 changes to WKT2_2019, included
in tests.
