Rust trait for constant #[repr(T)] conversions

• Const trait workaround for stable Rust exposing a safe transmute to the repr type with a trait
• Optionally-enabled const trait workarounds for generic integer and float operations and comparisons on the inherent representation
  • inherent: Providing AsReprInherent built on AsRepr but chooses a specific representation to interpret as for const operations
  • cmp: Providing const fns generic for comparable types
  • float: Providing const fns generic for floating point types
  • int: Providing const fns generic for integer types
  • num: Providing const fns generic for numeric types (floats and ints)
  • ops: Providing const fns generic for mathematical types (numeric types and Durations)
