Autogen: Add timestamp file for CMAKE_GLOBAL_AUTORCC_TARGET

When `CMAKE_GLOBAL_AUTORCC_TARGET` is ON and qrc files are not
generated, `<target_name>_arcc_data` is always dirty. So this commit
adds a timestamp file which depens on what `<target_name>_arcc_data`
depends before and ``<target_name>_arcc_data` depends the timestamp
file.

The dependency graph before
(qrcFile, InfoFile) -> _arcc_target

The dependency graph after
(qrcFile, InfoFile) -> global_rcc_timestamp ->_arcc_target

Fixes: #26059
