[lldb][lldb-dap] Redirect LLDB's messages to the right output category. (#137002)

Based on the DAP specification.
The output categories stdout and stderr should only be used for the
debuggee's stdout and stderr.

```jsonc
 /**
     * The output category. If not specified or if the category is not
     * understood by the client, `console` is assumed.
     * Values:
     * 'console': Show the output in the client's default message UI, e.g. a
     * 'debug console'. This category should only be used for informational
     * output from the debugger (as opposed to the debuggee).
     * 'important': A hint for the client to show the output in the client's UI
     * for important and highly visible information, e.g. as a popup
     * notification. This category should only be used for important messages
     * from the debugger (as opposed to the debuggee). Since this category value
     * is a hint, clients might ignore the hint and assume the `console`
     * category.
     * 'stdout': Show the output as normal program output from the debuggee.
     * 'stderr': Show the output as error program output from the debuggee.
     * 'telemetry': Send the output to telemetry instead of showing it to the
     * user.
     * etc.
     */
    category?: 'console' | 'important' | 'stdout' | 'stderr' | 'telemetry' | string;
```
What I am not sure if error should use the important category ?
