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

What do you think?

As an alternative, I think --forward-all-clicks could be deprecated.

It could be replaced by a new parameter --mouse-bind=xxxx. The argument would be exactly 4 characters, one for each secondary click:

--mouse-bind=xxxx
             ^^^^
             ||||
             ||| `- 5th click
             || `-- 4th click
             | `--- middle click
              `---- right click

The characters could be:

• +: forward the click
• -: disable the click
• b: trigger shortcut BACK
• h: trigger shortcut HOME
• s: trigger shortcut APP_SWITCH
• n: trigger shortcut "expand notification panel"

For example:

• --mouse-bind=bhsn (the default mode with SDK mouse)
• --mouse-bind=++++ forwards all clicks (would be the default mode in HID/AOA)
• --mouse-bind=++bh forwards middle and right click, and use 4th button for BACK and 5th button for HOME

This would provide a solution for #2258 (comment).
