VirtualKeyGroup Support for Modifier Type Keys

Is your feature request related to a problem? Please describe.
I would like to support creating key combinations using VirtualKeyGroup that involve modifier keys.

Describe the solution you'd like
The ability to check that "Shift+Q" IsPressed without having to press Shift and Q on the same frame. Normally the modifier key is pressed first and then the desired non-modifier key.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
I've created a branch to implement this here: https://github.com/JoltCrewStudios/stride/tree/modifier-virtualkey-group

Here are some questions that can aid in the description of the feature request:

• What are the usecases?
• What kind of options/settings are expected/wanted?
• What would the (pseudo) code look like?
• Is the feature affecting behaviour in the editor?
  • if so: how should this look in the editor?
• Is there a component or datastructure?
• what kind of documentation is needed or needs to be updated?
• Should there be an example project?

Review the modifier-virtualkey-group branch linked in the issue and trace the existing VirtualKeyGroup handling in Stride. Verify that a combination such as Shift+Q reports IsPressed when Shift and Q are pressed on different frames, and confirm the behavior is covered by the relevant input tests or a reproducible example.
