Android: Replace movement buttons with joystick (#7126)

* Android: Replace movement buttons with joystick Replace movement control buttons (arrows at bottom left screen) with virtual joystick. Joystick has 8 directions (same as keyboard). Basically, just map it to keyboard input. Joystick applies only on left 1/3 of screen. Joystick's position can be fixed by enabling fixed_virtual_joystick setting. Three new images: (1) placeholder joystick, (2) joystick container (background), and (3) joystick cursor. Remove unused images: movement control buttons (*_arrow.png). New data type: touch_gui_joystick_move_id Joystick's fixed position is spaced one button size from bottom and from left of screen. Remove unused variable: m_joystick_downlocation
