The TTD adapter replays a recorded trace, but nothing checked that one was actually configured, so launching without a trace path failed deep inside the engine with an opaque "OpenDumpFile failed: 0x..." HRESULT. Validate the trace path in AdapterSettingsDialog::apply() and keep the dialog open with an explanation instead of accepting it. The settings view writes each value as it is edited, so the current value can simply be read back; no changes to SettingsView are needed. The check is limited to the launch group with the DBGENG_TTD adapter selected so the other flows are unaffected. Also check the trace path in DbgEngTTDAdapter::ExecuteWithArgsInternal before starting the engine, which covers the headless and scripted paths as well as the launches where the settings dialog is skipped (#1133).

Fixes #910.
This PR fails the TTD launch attempt and gives a meaningful error message (rather than the cryptic OpenDumpFile failed with xxxxx)
The check are both added in the UI and the debug adapter
