Replaces uses of CoglAngle with floats (Though the CoglAngle type remains)

The CoglAngle type can still be used for focused optimisations since the type
and macros remain. Uses of CoglAngle within Cogl have been replaced with floats;
COGL_ANGLE_FROM_DEG is no longer used anywhere and the replacements for
cogl_angle_cos -> cosf (same for sin) have been fixed to convert float values
in degrees to radians. This fixes the cogl-primitives API.
