Strongly typed angle constants.

These allow common constants used as angles to be strongly typed (so it’s possible to write Angle::<f32>::PI instead of Angle::radians(core::f32::PI)).

Note that this is also the most convenient way to get these constants in a const context. Since Angle is a generic type, the Angle::from_radians() constructor cannot be invoked in a const context. This is also why num_traits::FloatConst is not good enough.
