As proposed in #414, this commit changes the backend selection approach, introspecting `target_pointer_width` to select `u32_backend` vs `u64_backend` (or `fiat_u32_backend`/`fiat_u64_backend` if the `fiat_backend` feature is enabled). This helps eliminate the use of non-additive features, and also the rather confusing errors that happen if multiple backends are selected (i.e. thousands of lines of rustc errors). The selection logic checks if `target_pointer_width = "64"` and uses the 64-bit backend, or falls back to the 32-bit backend otherwise. This means the crate will always have a valid backend regardless of the pointer width, although there may be odd edge cases for exotic platforms which would optimally use the 64-bit backend but have a non-"64" target pointer width for whatever reason. We can handle those cases as they come up.
