Windows: prevent unsupported EFI Secure Boot fallback

Browse Source 
Detect whether the active firmware Secure Boot db trusts the Microsoft Corporation UEFI CA 2011 before selecting the 2011-signed EFI loader set.

Abort with a clear diagnostic when Secure Boot is enabled but neither the 2011 CA nor the required 2023 CA pair is trusted, and document the CA requirements.

Preserve positive CA detection when malformed db data appears only after a supported Microsoft CA set has already been found, while recording the parse error in diagnostics.

Refs #1778.
