[rcore] fix gamepad axis movement and its automation event recording

Browse Source 
This commit fixes 2 issues:
- Automation events aren't recorded for negative axis movements on
  gamepads (e.g. stick going left/up)
- 'GetGamepadAxisMovement' drift check isn't working correctly for
  triggers. Axis values between [-0.1, 0.1] are clamped to 0.0

Behaviour change:
- 'GetGamepadAxisMovement' returns default value for each axis, even
  if gamepad isn't attached.
