Force Screen orientation not affecting accelerometer input [Android]

Is there an existing issue for this?

• This is a bug in RetroArch frontend
• I have searched the existing issues

Description

Force Screen Orientation under video settings doesn't affect Accelerometer as expected.

Playing Kirby Tilt N Tumble on mGBA supports Android accelerometer, but it is off by 90°. (Ex. Left is down)

I found this fix: https://github.com/libretro/RetroArch/issues/6535#issuecomment-495315228

However, when forcing screen orientation the accelerometer gives the same results no matter the orientation I pick.

Force Video orientation allows me to play correctly, but then I have to hold my device sideways, which isn't ideal.

Expected behavior

Force Screen Orientation should also set the on device Accelerometer orientation.

Steps to reproduce the bug

1. Load an accelerometer-based game (tilt n tumble)
2. Switch Force Screen Orientation in video settings

Relevant log output

Start by reproducing the issue on Android with Kirby Tilt ’n’ Tumble in mGBA, then trace the Force Screen Orientation video setting and the accelerometer input path. Done means changing the forced orientation also rotates the accelerometer input consistently, without requiring the device to be held sideways.
