Add Copy and Dismiss Button in RN Android Red Box

Summary:
Add "Copy" and "Dismiss" button when the RN Android redbox is shown, consistent with that in RN iOS.
  - "Copy" button copies all the messages shown in the redbox to the host system clipboard, the solution is posting redbox messages to packager and the the packager copies the messages onto the host clipboard.
  - "Dismiss" button always exits the redbox dialog.
  - Add shortcut as "Dismiss (ESC)" and "Reload (R, R).

Notice: Copy button is only supported on Mac OS by now (warning in packager on other platforms), because it's not easy for us to test on Windows or Linux. Will put the codes for other platforms on Github issues, hoping anyone could help test and add this feature, then send us a pull request.

Redbox Dialog in RN Android before:
{F61310489}
Redbox Dialog in RN Android now:
{F61659189}

Follow-up:
- We can adjust the button styles in redboxes.
- We can consider to add shortcut for "Copy" button.
