[Feature] Add resizeToAvoidBottomInset to ScaffoldPage

[henry2man]

Is your feature request related to a problem? Please describe.
On mobile, when virtual keyboard is shown the UI doesn't adapt to the constrained viewPadding. In FluentUI we don't have an equivalent for Scaffold.resizeToAvoidBottomInset

Describe the solution you'd like
Add bool? resizeToAvoidBottomInset = true to ScaffoldPage in order to have a proper responsive UI on mobile and/or with virtual keyboards.

Describe alternatives you've considered
In order to have a system-wide behavior I've used this workarround:

// On every route that may show a virtual keyboard
SafeArea(
  child: Padding(
      // Add bottom padding
      padding: EdgeInsets.only(
          bottom: MediaQuery.of(context).viewInsets.bottom),
      child: YourWidget()))

Additional context
This is current behavior:

Current workaround is this:

// On every route that may show a virtual keyboard
SafeArea(
  child: Padding(
      // Add bottom padding
      padding: EdgeInsets.only(
          bottom: MediaQuery.of(context).viewInsets.bottom),
      child: YourWidget()))

If we add resizeToAvoidBottomInset property we may adapt it to apply existing ScaffoldPage paddings, if any.
