ci: save the emulator state when the Android e2e job fails

[plum117]

Why

The Android emulator job sometimes fails because the emulator is in a bad state for the whole job: the screen under the status bar is black, and taps and key events fail. The full page tests then fail with the viewport of the mobile browser is not known (height 0) (#1334).

Run	PR	Overlay height 0	Cannot generate key press event
38027305572	—	20 / 20	16 / 16
39050523321 (attempt 1)	#1348	20 / 20	16 / 16
39158355600 (attempt 1)	#1357	20 / 20	16 / 16

It starts with the warm-up session and stays in the next session, although each session stops and starts Chrome again. So the emulator is in a bad state, not only Chrome. A rerun on a new runner passes. The uploaded artifacts have only the Appium log and the screenshots, so the cause is not known.

What

.github/scripts/android-emulator-e2e.sh: when the script fails, it saves the device state in logs/device/ before the action stops the emulator. The job already uploads logs/ on failure.

• screen.png (adb exec-out screencap)
• logcat.txt
• dumpsys-window.txt, dumpsys-activity.txt, dumpsys-input.txt, dumpsys-power.txt, dumpsys-display.txt, dumpsys-SurfaceFlinger.txt

Each command has a timeout and cannot change the exit code. A job that passes runs none of them. A CI change only, so there is no changeset.

Test

• With a stub adb: a failing script keeps exit code 1 and saves the 8 files; a passing script calls no adb command.
• shellcheck: no findings.
• The Android emulator job of this PR runs the changed script (normal path).
