Small change to get `image dump separate-debug-info` working when using
`symbols.load-on-demand`.
Added tests to `TestDumpDwo`, and enabled the test for all platforms. If we fail to build, we skip the test, so this shouldn't cause the test to fail on unsupported platforms.
```
bin/lldb-dotest -p TestDumpDwo
```
It's easy to verify this manually by running
```
lldb --one-line-before-file "settings set symbols.load-on-demand true" <some_target>
(lldb) image dump separate-debug-info
...
```

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.

PR#66035 introduced a test failure that causes windows build bots to
fail. These unit tests shouldn't be running on Windows.
