Update Xbox BT controller mapping to support upcoming controller firmware update
The Xbox controller (product id 0x2fd) is going to have a new firmware update this fall that sends a different keycode (316/BUTTON_MODE) for the Xbox button. The goal is to enable the Xbox button to make it to apps on all Android versions -- with our without a controller-specific key mapping file. Unfortunately, the new Vendor_045e_Product_02fd.kl key mapping file that was added to Android Q maps the pre-firmware-update Xbox key code (172) to BUTTON_MODE, yet it makes no mention of key 316. This results in apps getting a raw 316 scan code instead of a BUTTON_MODE KeyEvent when using a controller with the latest firmware on Android Q. The fix is to add an additional key mapping for 316 that *also* maps to BUTTON_MODE. With both mappings in place, both pre and post firmware-updated controllers will get the correct behavior for the Xbox button on Android Q. Test: AFAIK, no CTS tests exist for Xbox controller key mappings; we'll need to add some at a later date. I was unable to test this change because I'm unable to write to the system directory on any of my devices, but I know that mapping 316 to BUTTON_MODE will fix the issue.
