Part of #17297

[Copilot]

Pull request overview

This PR upgrades the type strictness level from typed: true to typed: strict for the Library/Homebrew/patch.rb file as part of the gradual migration to stricter typing (#17297). The changes add comprehensive Sorbet type signatures throughout the file and remove tests that are no longer applicable due to the type system enforcing constraints that were previously tested manually.

• Added Sorbet type signatures to all methods and instance variables
• Marked EmbeddedPatch as abstract with proper abstract method declarations
• Removed error handling for invalid input types that the type system now prevents
• Removed tests for error cases that are now type-level guarantees and for the abstract EmbeddedPatch class that can no longer be instantiated directly
