Type features

[bitshifter]

Objective

• As glam has accumulated more types over time compile times have greatly increased. This PR makes most types optional so they can be disabled if that are not used to reduce compile times back to the good old glam days.
• Fixes Slow compile times? #726

Solution

• All types can be disabled excepted for f32 and bool. All types are enabled by default but users can disable default features and enable only the types that they use.

Breaking changes

If default features are disabled then users will need to re-enable any types that they are using.
