  Log Message:
  -----------
  [lldb][split-dwarf] Add --errors-only argument separate-debug-info list (#71000)

Often, we only care about the split-dwarf files that have failed to
load. This can be useful when diagnosing binaries with many separate
debug info files where only some have errors.

```
(lldb) help image dump separate-debug-info
List the separate debug info symbol files for one or more target modules.

Syntax: target modules dump separate-debug-info <cmd-options> [<filename> [<filename> [...]]]

Command Options Usage:
  target modules dump separate-debug-info [-ej] [<filename> [<filename> [...]]]

       -e ( --errors-only )
            Filter to show only debug info files with errors.

       -j ( --json )
            Output the details in JSON format.

     This command takes options and free-form arguments.  If your arguments
     resemble option specifiers (i.e., they start with a - or --), you must use
     ' -- ' between the end of the command options and the beginning of the
     arguments.

'image' is an abbreviation for 'target modules'
```

I updated the following tests
```
# on Linux
bin/lldb-dotest -p TestDumpDwo

# on Mac
bin/lldb-dotest -p TestDumpOso
```

This change applies to both the table and JSON outputs.
