feat(): support multiple as a default preset method

[devversion]

• Dialogs, Bottom-Sheets and Toasts have presets, which all depend on the build preset automatically.
• Due to the new muliple property in the $$interimElement factory, developers can explicitly pass the multiple property per JSON, but not as a preset method.

@ThomasBurleson: This just creates an alias for the given option.

@devversion - what is the issue that this resolves ?

[devversion]

@ThomasBurleson This is a followup PR to the #9053, which just provides the "new available" option in the default preset - This is a step forward to #8630

[ThomasBurleson]

@devversion - If we consider our planned changes to $mdCompile and use of the Component API & mdPanel, is this necessary ?

[devversion]

@ThomasBurleson This does not interfere with anything of that. It just provides the alias of the multiple flag, which was not added in the original PR.

Right now you can do

$mdDialog({
  multiple: true
}

But to be consistent with all "available" options for the $$interimElement, the preset should also have a method for this

$mdDialog(
  $mdDialog
    .build()
    .multiple(true)
);

All available options should be added to that methods array.
