SYSTEM UNFREEZE command will not try

The SYSTEM UNFREEZE command will not try to look up parts in readonly and write-once disks. This closes #80430. #80432 (Alexey Milovidov).
The SYSTEM UNFREEZE command no longer attempts to look up parts in readonly and write-once disks.

Why it matters

This feature addresses the issue where SYSTEM UNFREEZE inefficiently checks readonly and write-once disks for parts, which are not eligible for unfreeze operations. By skipping these disks, it improves command performance and avoids unnecessary operations.

How to use it

Users can run the SYSTEM UNFREEZE command as usual. The command now automatically excludes readonly and write-once disks from part lookup without requiring any additional parameters or configuration.
