Revert "Output number of characters added to file (Bug#354)"

The extra message text turned out to be quite annoying in practice,
and is generally more trouble than it's worth.  Also revert several
related changes.

Partially revert "Handle `write-region' messages in Tramp properly"
Revert "New var write-region-verbose, default nil"
Revert "* src/fileio.c (write_region): Don't say "1 characters".  (Bug#26796)"
Revert "Minor tuneup of write-region change"
Revert "Adjust write-region so file name is at the beginning again"
Revert "Fix handling of non-integer START param to write-region"
Revert "Output number of characters added to file (Bug#354)"
