Add ReportActivity and ReportInfo

This implements the framework to report info to users. This may include reporting failure or result of commands or any exceptions that are raised.

The ReportInfo provides 5 fields:
- userAction: The user action that was being processed for which the report was generated.
- sender: The internal app component that sent the report.
- title: The report title.
- reportString: The markdown text for the report.
- addReportAndDeviceDetails: If set to true, then report and device details will be added to the report.

This should provide the basics parameters for showing a report to the user. The ReportActivity also allows user to copy and share the report.

In future this can also be used to allow users to easily email or post crash reports to github for Termux app crashes instead of going through logcat.
