Doxygen alias support

Type: Feature Request

This is similar (if not identical) to https://github.com/microsoft/vscode-cpptools/issues/5700 - adding support for Doxygen aliases like @par instead of @param, @input instead of @param[in] etc.

My use-case is probably unique, working on a large codebase documented with SourceDoc [2], an older source documenting tool that uses a syntax which overlaps a lot with Doxygen and can be parsed by Doxygen specific tools (including cpptools) with the appropiate aliases.
However, generic Doxygen alias support is probably not that rare and might help others too.

Ideally, aliases would allow setting the display name in the hover, but for the regular Doxygen parsing those seem to be localized, so that part might be tricky.

If aliases are hard to implement, maybe we could at least define our custom tags and their hover diplay name.

Disabling Simplify Structured Comments is not a viable alternative, the result is too much of paragraph soup to be intelligible, we cannot customize the sections to be filtered in the hover etc.

Code example:

/**
 * @function cpptools_test1
 * @brief desc for this void func.
 *
 * @input   p1    Input arg.
 * @output  p2    Output args.
 */
static void
cpptools_test1(void *p1, void *p2)
{
   (void)p1;
   (void)p2;
}

Die Anfrage nennt keine Implementierungsdateien oder Tests. Beginnen Sie mit der Durchsicht der verlinkten Doxygen-Alias-Dokumentation und des bereitgestellten C-Beispiels; klären Sie, ob Aliase, benutzerdefinierte Tags und Hover-Anzeigenamen erforderlich sind, und überprüfen Sie anschließend, dass Tags wie @input und @output wie vorgesehen geparst werden.
