ExternalProject: Add DOWNLOAD_EXTRACT_TIMESTAMP option and policy

Browse Source 
Add the option to keep the current filestamps when extracting an
archive in ExternalProject_Add.

Enabling this option makes the behavior consistent with how
ExternalProject_Add is used when checking out code from revision
control instead of an archive.

Fixes: #22746
