363: scb: derive serde, Hash, PartialOrd for VectActive behind gates r=thalesfragoso a=tmplt

Exposes two new feature gates for VectActive serde::{Serialize,
Deserialize} (via "serde") and Hash, PartialOrd (via "std-map") for use
on host-side ITM tracing programs. While the struct itself is not
received directly over ITM, its use greatly simplifies the
implementation by allowing VectActive as keys in map collections and
file/socket {,de}serialization to forward the structure elsewhere. These
features are not enabled by default.

Before this patch, serde functionality could be realized via [0], but
this does not propagate down a dependency chain (i.e. if realized for
crate B, which crate A depends on, serde functionality is not exposed in
crate A unless VectActive is wrapped in a type from crate B). I am not
aware of any method to realize PartialOrd, Hash derivation for a
downstream crate.
