Forward all clicks by default for UHID and AOA

[rom1v]

In relative mouse modes (when the cursor appears on the device), it makes more sense to forward all clicks (disable HOME/BACK shortcuts on secondary clicks).

Transform the boolean option --forward-all-clicks into a 3-state option:

• --forward-all-clicks=true or --forward-all-clicks: enable
• --forward-all-clicks=false: disable
• --forward-all-clicks=auto (default): enable only for UHID and AOA

That way, by default, all clicks are forwarded with scrcpy -M.

Or maybe it would be more consistent to keep --forward-all-clicks as a boolean option, and add a new --no-forward-all-clicks:

# SDK mouse: forward all clicks is disabled
scrcpy
# UHID mouse: forward all clicks is enabled
scrcpy -M

# SDK mouse: force enabled
scrcpy --forward-all-clicks
# UHID mouse: force disabled
scrcpy -M --no-forward-all-clicks
