Most recent distros have a newer version of cmake.
The notable distros that don't ship 3.25 are:
- Ubuntu 22.04 LTS (EOL 2027)
- Debian 11 Bullseye (EOL since 31 August 2026)
They have options to install a newer cmake.
Get rid of a warning in RustHelper.cmake by setting DOWNLOAD_EXTRACT_TIMESTAMP (introduced in 3.24)
Depends on D20546
