Reduce the verbosity of optdata sync on stdout (#12543)
Reduce the verbosity of optdata sync on stdout (#12543)

Set the "StandardOutputImportance" attribute on the RestoreOptData
target to low, matching the "RestoreNETCorePlatforms" target. Logging
to sync.log remains verbose, but stdout on the console is made much less
verbose.

Fixes #12127
