feat(types): Add gRPC Richer Error Model support (BadRequest) (#1068)

* types: add tonic as dependency, add error_details.proto

* types: add BadRequest support from flemosr/tonic-richer-error

* types: adjust code following suggestions

Adjustments following suggestions by @LucioFranco in https://github.com/hyperium/tonic/pull/1068.

Adjust style, remove unecessary prints, avoid glob imports, apply
`non_exhaustive` to `ErrorDetails` and `ErrorDetail`, avoid pub
fields in `ErrorDetails`, adjust
`WithErrorDetails::with_error_details_vec` args, add
`gen_details_bytes`.

* types: add generated protobuf code

As suggested by @LucioFranco in https://github.com/hyperium/tonic/pull/1068#discussion_r956117520.

This avoids the need for consumers to have `protoc` in their path.
Implemented following changes in https://github.com/hyperium/tonic/pull/1065.

* types: add custom metadata support

This allows consumers to provide custom metadata when creating a
`Status` with error details.

* types: adjust code following suggestions

Adjustments following suggestions by @LucioFranco in https://github.com/hyperium/tonic/pull/1068.

Move `error_details_vec` mod into `error_details` mod, adjust doc
comments, rename `WithErrorDetails` trait to `StatusExt`.
