CURLOPT: bump CURLWS_NOAUTOPONG, CURLWS_RAW_MODE macros to long

This patch bumps the size of these macros from `int` to `long`, while
keeping their actual values the same. It may cause incompatibilities in
user code, requiring the bump of holder variables and/or adding casts:

- CURLWS_NOAUTOPONG
- CURLWS_RAW_MODE

Also:
- keep existing cast within the documentation to make sure it applies
  to older curl versions as well.

Closes #18137
