On Android the render thread runs the UI, and surfaceDestroyed waits for
it, so slow storage (SAF especially) there stutters and can become an ANR.
- Store: only check whether the game is installed when an install or
uninstall finishes, not every frame.
- Savedata: read the modification time with SIZE on the GameInfo worker.
The popup asked for it every frame, and each button on first draw.
- FirmwareScreen: scan the NAND, and erase it, on a worker thread. It
rescanned on every RecreateViews, which is after every popup.
- GameScreen: look up the installed update, plugins and what the firmware
can play on a worker thread. They ran on every RecreateViews, which
happens as each piece of game info arrives.
- LaunchFile: wait only for the file type, and for PARAM.SFO just in the
cases that use it.
Also add --start-screen=firmware.
