Blazor server performance improvements

[javiercn]

There are several performance improvements that we can make to reduce the bandwidth used by Blazor Server. Enabling compression requires us to investigate potential security issues with regards to HTTPS, packing the frames more tightly seems to offer a 30% improvement over the frame size, finally we can "minimize" some of our JS interop callbacks to reduce the size a bit further.

• Enable compression on blazorpack #35897
• For server-side Blazor, consider packing the reference frames more tightly #12306
• Reduce Data Flow #13025
• Shrink blazor.*.js file size, SignalR Minification #37260
• More integration for Blazor Server and SignalR #38109
