Add support for specifying a launch profile to `dotnet watch run`

[DamianEdwards]

As part of [EPIC] Revisiting HTTPS defaults in ASP.NET Core

ASP.NET Core projects are being updated to have multiple launch profiles by default. As such, we'd like it to be easier to select a launch profile when running the project using dotnet watch/dotnet watch run.

We propose supporting -lp as an option alias for --launch-profile, e.g.:

$ dotnet watch -lp https

Is this related to #38408 in any way?

Not directly, I think, but the existing logic within dotnet watch to select the launch profile it uses may well have some determinism issues.
