CMake: Handle generated headers in syncqt scan all mode for docs

Building the docs of the Network module can result in incomplete
documentation in the following scenario:
- use an external prebuilt qdoc
- configure the module with QT_SYNC_HEADERS_AT_CONFIGURE_TIME=OFF
- call cmake --build . --target html_docs_Network

In this case the qdnslookup.html file is missing the whole block
for QDnsLookup::finished.

The reason is that the 'prepare_docs_<module>' target only depends on
'sync_all_public_headers', which runs syncqt with the '-all' option.

In that mode syncqt ignores the header list given via '-headers' and
scans the module source directory instead. Generated headers are never
processed, so they don't get a forwarding header. In qtbase that
doesn't create qt<module>-config.h and qt<module>-config_p.h headers.

Without them qdoc can't find QtNetwork/private/qtnetwork-config_p.h
which leaves QT_FEATURE_dnslookup undefined, the
QT_REQUIRE_CONFIG(dnslookup) condition fails, and some of the code is
not parsed.

To fix this, pass and process the '-generatedHeaders' list in the
'scan all' mode as well.

The headers that are excluded from docs are filtered out, so doc
generation still doesn't depend on headers that need a tool to be
created, like the dbus generated ones.

The issue doesn't show up in a developer build, because
QT_SYNC_HEADERS_AT_CONFIGURE_TIME defaults to ON there and syncqt has
already created the forwarding headers at configure time.

In a qt5.git super builds it doesn't happen either because
'prepare_docs_<module>' depends on the 'qdoc' target, which
links QtQml and QtNetwork, which in turn pulls in the regular
'<module>_sync_headers' targets.
