gen_stub: documentation updates

* Use `@param` instead of `@var` for parameters
* Fix type of `$attributeGroups` in `AttributeInfo::createFromGroups()`
* Remove extra documentation of `$allConstInfo` for
`ClassInfo::getClassSynopsisDocument()`, it is already documented under the
correct name `$allConstInfos`
* Remove unneeded `@throws`
