Align SVC and low delay settings with VT SW encoder capabilities

- `GetSupportedH264Profiles()` is tuned to only list L1T1 (de facto no
  scalability) as a supported scalability mode for the software encoder.

- Low latency and SVC will now only be enabled for hardware encoders to
  avoid errors in software encoders.

- The check for encoder mode (hardware or software) is extended to work
  around an issue where a low-delay VideoToolbox encoder is misrepresented
  as a software encoder.

This makes the `webcodecs` suite of GPU integration tests pass in
`media_use_openh264=false` builds.
