Added Whisper Factory Options

[sandrohanea]

As the options for creating a WhisperFactory were growing, took the initiative to migrate some of the options that are reusable to WhisperFactoryOptions and removing them from RuntimeOptions.

Now, RuntimeOptions remains only for Library loading (whisper.cpp Runtime) and any other options like GPU device, DTW options, etc. can be defined for each factory independent on the library itself.

• The ArgumentOutOfRangeException should include a more descriptive error message.

throw new ArgumentOutOfRangeException(nameof(preset), preset, null);

• The variable 'aheadsHandle' is being redefined unnecessarily. It should use the existing 'aheadsHandle' field.

ModelLoaderUtils.GetWhisperAlignmentHeads(options.CustomAlignmentHeads, out var aheadsHandle);

• [nitpick] The parameter names textLayer and head should follow the naming convention and be renamed to TextLayer and Head respectively.

• [nitpick] The property name 'TextLayer' is ambiguous. It should be renamed to 'LayerIndex' for better clarity.

public int TextLayer { get; } = textLayer;
