Improve Shared Fonts + Fix AM PopLaunchParameter & Choreographer Bug

* Move Shared Font TTFs to AAsset storage + Support external shared font loading from `/data/data/skyline.emu/data/fonts`
* Fix bug in `IApplicationFunctions::PopLaunchParameter` caused by ignoring `LaunchParameterKind`
* Fix bug with Choreographer causing it to be awoken and exit prior to the destruction of `PresentationEngine`
* Fix bug with `IDirectory::Read` where it used `inputBuf` for the output buffer rather than `outputBuf`
* Improve `GetFunctionStackTrace` logs when `dli_sname` or `dli_fname` are missing
* Support more RT Formats
