Add new copy_files build mode

[isaacroldan]

WHY are these changes introduced?

To support a new build mode for extensions that allows copying specific files to the output directory based on configurable patterns.

WHAT is this pull request doing?

Adds a new copy_files build mode for extensions that:

• Allows specifying file patterns to include in the build output
• Supports ignoring specific file patterns
• Maintains the directory structure when copying files
• Provides appropriate build output messages

The implementation includes:

• Updated type definitions for BuildConfig to support the new mode
• New copyFilesForExtension function to handle the file copying logic
• Comprehensive tests for the new functionality
• Integration with the existing extension build system

How to test your changes?

1. Create an extension with the following build configuration in its specification:

"buildConfig": {
  "mode": "copy_files",
  "filePatterns": ["*.json", "assets/**/*.png"],
  "ignoredFilePatterns": ["test/**"]
}

1. Run shopify app build
2. Verify that only files matching the patterns are copied to the output directory
3. Verify that files in ignored directories are not copied

Differences in type declarations

We detected differences in the type declarations generated by Typescript for this branch compared to the baseline ('main' branch). Please, review them to ensure they are backward-compatible. Here are some important things to keep in mind:

• Some seemingly private modules might be re-exported through public modules.
• If the branch is behind main you might see odd diffs, rebase main into this branch.
