[Feature Request] Add Secure Boot as a Hyper-V option

**What are you trying to do?**
Allow VM's to be marked for Secure Boot

**What's your proposed solution?**
Unsure.

**Additional context**
By default, VM's made by Multipass do not have Secure Boot enabled (although the images support it).

Can we have it set to "Microsoft UEFI Certificate Authority" by default or have a switch like `--name`? `--secure-boot`

Start by tracing Multipass's Hyper-V VM creation path and how the existing --name option is parsed; the issue does not identify specific files or tests. Determine whether Secure Boot should be enabled by default or exposed through a --secure-boot switch, using the Microsoft UEFI Certificate Authority setting. Done means Hyper-V instances can be created with the requested Secure Boot behavior and the choice is covered by tests.
