Joystick sensitivity for player movement (#11262)

This commit deprecates the forward, backward, left, and right binary
inputs currently used for player movement in the PlayerControl struct.
In their place, it adds the movement_speed and movement_direction
values, which represents the player movement is a polar coordinate
system.

movement_speed is a scalar from 0.0 to 1.0. movement_direction is
an angle from 0 to +-Pi:

	       FWD
	        0
	        _
	 LFT   / \   RGT
	-Pi/2 |   | +Pi/2
	       \_/
	       +-Pi
	       BCK

Boolean movement bits will still be set for server telegrams and
Lua script invocations to provide full backward compatibility.
When generating these values from an analog input, a direction is
considered active when it is 22.5 degrees away from either
orthogonal axis.
