Add Microsoft.Windows/OptionalFeatureList resource

[SteveL-MSFT]

PR Summary

Add Microsoft.Windows/OptionalFeatureList resource to manage Windows Optional Features.
Supports get, set, and export each requiring elevation
get and set require featureName to be present and exact match
get will return _exist=false when attempting to retrieve a non-existing feature
export allows featureName, displayName, description to have wildcard matching case-insensitive.
For export if multiple objects are used as input, each object's properties is a logical AND while each individual object is a logical OR

Pull request overview

Adds a new Windows-only DSC resource (Microsoft.Windows/OptionalFeatureList) implemented as a Rust executable (dism_dsc) that manages Windows Optional Features via the DISM API, with manifests/localization and Pester integration tests.

Changes:

• Introduces the dism_dsc Rust crate with get, set, and export operations backed by DISM (dynamic loading + session wrapper).
• Adds the DSC resource manifest + embedded JSON schema and localized strings.
• Adds Pester tests for get/set/export, and wires the crate into the workspace (Cargo.toml/Cargo.lock).
