[EPIC] Send full list of debug meta for app start transactions

[philipphofmann]

For the mobile Starfish library size and count widget, we plan on adding statistics on the number of loaded libraries and their size during the app start. We decided to use the existing debug_meta payload that transactions already use when containing file IO on the main thread spans. Therefore, app start transactions must send the full list of all debug_meta. Most SDKs have an optimization to only send debug_meta referenced in the stacktrace to reduce the event payload size. For app start transactions, this optimization must be bypassed.
