Alexandre Courbot e4ead68a39 rust: transmute: add from_bytes_prefix family of methods
The `from_bytes*` family of functions expect a slice of the exact same
size as the requested type. This can be sometimes cumbersome for callers
that deal with dynamic stream of data that needs to be manually cut
before each invocation of `from_bytes`.

To simplify such callers, introduce a new `from_bytes*_prefix` family of
methods, which split the input slice at the index required for the
equivalent `from_bytes` method to succeed, and return its result
alongside with the remainder of the slice.

This design is inspired by zerocopy's `try_*_from_prefix` family of
methods.
