cmake: publish/check supported protocols/features via CURLConfig.cmake
Via these variables, as lists:
- `CURL_SUPPORTED_PROTOCOLS`
- `CURL_SUPPORTED_FEATURES`

As individual flags:
- `CURL_SUPPORTS_<protocol/feature>` = `TRUE`

Also:
- set `CURL_VERSION_STRING` which was missing when using
  `find_package(CURL CONFIG)` or
  `find_package(CURL NO_MODULE)`.
- set `CURL_<prototol/feature>_FOUND` for compatibility.
- show full list of missing but required `COMPONENTS`.

Closes #15858
