Maximum allowed files for Blazor InputFile component

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

This is followup to https://github.com/dotnet/aspnetcore/issues/47036

@javiercn was right, this is due to maximum signalr message size.

However setting limit in method `e.GetMultipleFiles(Constants.MaxImageCount)` will not work as expected, because it will never be called. When uploading 300 files, signalr connection is lost and reconnected. Input box is showing, that file count is 300, but there is nothing you can do about it.

### Expected Behavior

I believe there should be a way to either split this to multiple messages via signalr, or at least make a way to show an error when there is more than X files selected.

### Steps To Reproduce

Try to upload 300 files using `InputFile` blazor component
