Deprecate and Remove AppMetadataManager

This pull request removes the deprecated AppMetadataManager class and encourages usage of the BuildProfiler class for accessing application metadata.

Background:

The AppMetadataManager class has been marked as deprecated in favor of the more robust BuildProfiler class. This pull request completes the deprecation process by removing the redundant class entirely.

Removal:

The entire AppMetadataManager.kt file containing the deprecated class has been removed from the codebase.

Alternative:

• For accessing application metadata (version details, build information, etc.), leverage the BuildProfiler class.
• LocalBuildProfiler.current provides methods to retrieve specific data points previously offered by AppMetadataManager.

Benefits:

• Promotes code cleanliness by eliminating unused and deprecated code.
• Encourages use of the recommended and actively maintained BuildProfiler class.
• Improves code clarity and maintainability.
