Oliver Wolff 2412cfac51 moc: Fix parsing of [[deprecated]] enum values
moc now successfully parses enum values, that have been deprecated with
[[deprecated]]. This is valid c++17 and should be handled correctly.
By adding that functionality it is possible to parse Windows headers
which use this deprecation mechanism.

To make sure, that moc works correctly even on compilers that do not
support deprecated enum values yet, the auto test explicitly uses
[[deprecated]] enum values during moc run.

Fixes: QTBUG-74126
