feat!: disable console wallet grpc (#5988)

Description
---
Disabled the console wallet gRPC via a feature flag in the console
wallet build configuration, where gRPC is not part of the default build.
Trying to run with the console wallet with the config option
`grpc_enabled = true` where the gRPC feature is not enabled for the
build will result in a runtime error.

Motivation and Context
---
See #5930

How Has This Been Tested?
---
Existing unit and cucumber tests pass

What process can a PR reviewer use to test or verify this change?

<!-- Checklist -->
<!-- 1. Is the title of your PR in the form that would make nice release
notes? The title, excluding the conventional commit
tag, will be included exactly as is in the CHANGELOG, so please think
about it carefully. -->


Breaking Changes
---

- [ ] None
- [ ] Requires data directory on base node to be deleted
- [ ] Requires hard fork
- [x] Other - The console wallet must be build with the `features =
["grpc"]` to enable gRPC

<!-- BREAKING CHANGE: Description what the user should do, e.g. delete a
database, resync the chain -->
