Add Microsoft/FileContent resource

[Steve Lee (SteveL-MSFT)]

Adds a cross-platform DSC resource for managing UTF-8 file content and verifying file integrity without exposing content from normal get operations.

Summary

• Implements Microsoft/FileContent in Rust with get, set, explicit test, and export operations.
• Computes SHA-256 and SHA-512 hashes using streamed file reads.
• Compares content-only test input by hashing the desired UTF-8 content.
• Supports file removal through _exist: false.
• Returns content only from export while get returns file identity, existence, and hashes.
• Adds the executable and resource manifest to Linux, macOS, and Windows package payloads.

Testing

• Rust formatting and pedantic Clippy checks
• Rust package build and tests
• 9 cross-platform Pester tests covering get, set, test, export, and deletion

Pull request overview

Adds a new cross-platform DSC resource (Microsoft/FileContent) implemented in Rust to manage UTF-8 file content via set, verify integrity via get/test hash outputs, and emit full content only via export. This extends the resource catalog and updates packaging/build inputs so the new resource ships across Linux/macOS/Windows.

Changes:

• Introduces the filecontent Rust resource executable with get/set/test/export operations, i18n strings, and a v3 resource manifest/schema.
• Adds cross-platform Pester coverage for get/set/test/export and delete (_exist: false) behavior.
• Registers the new resource in the workspace/build metadata and package payload lists.
