Common utilities for HAL<->TA communication
- Definition of an `AsCborValue` trait that marks a type as serializable
to/from CBOR. Adapted from `system/authgraph/wire/src/cbor.rs` with
the following differences:
- `CborError::NonEnumValue` gets an `i32` field to indicate what the
invalid value was.
- Add implementation of `From<TryReserveError>` for `CborError`.
- Add implementation of `AsCborValue` for `Vec<T : AsCborValue>`.
- Add implementation of `AsCborValue` for `bool`.
- Add implementation of `AsCborValue` for `i64`.
- Derive macro to automatically generate implementations of the
`AsCborValue` trait for types. Adapted from
`system/authgraph/derive/` with the following differences:
- Use types from `hal_wire::` rather than assuming the relevant
symbols are in `use`.
- Add `AsCborValue` derivation for newtypes (`struct` with single
anonymous field).
- Helper code (in `mem.rs`) to deal with fallible allocation. Adapted
from `system/authgraph/core/src/lib.rs` and
`system/keymint/wire/src/lib.rs`.
