Add Chrome homepage + startup tabs mirroring Edge config

Chrome (installed by PPKG) now gets the same profile-driven homepage
and startup tabs as Edge. Uses HKLM:\SOFTWARE\Policies\Google\Chrome
with the same policy keys (RestoreOnStartup, RestoreOnStartupURLs,
HomepageLocation, HomepageIsNewTabPage, ShowHomeButton).

Reuses the $startupTabs and $homepageUrl already resolved for Edge
from the PC profile, so both browsers show identical tabs. Skips
cleanly if Chrome isn't installed.
