Anatol Belski 051a6eff5c block: Add query_device_size() for file and block device size ...

Add a shared helper that returns the logical size in bytes for both
regular files and block devices using an immutable &File reference.

Regular files use metadata().len(). Block devices use the BLKGETSIZE64
ioctl. Any other file type returns an InvalidInput error.

This avoids seek(SeekFrom::End(0)) which requires &mut self and can
return incorrect results for block devices when the file position is
in an unexpected state.
