meta.trait: Deprecate one-liner 

These one-liners are useful for meta-programming but they can be easely
implemented. It isn't possible to implement all possible variants in a
generic library, so it is better they are defined in the user code.

Deprecated traits:
- isPOD
- sizeOf
- alignOf
- isSame
- isTemplate
- isInterface
- isClass
- isStruct
- isEnum
