fix: implement Amino serialization for x/authz and x/feegrant (cosmos…

…#11224) * fix: Add RegisterLegacyAminoCodec for authz/feegrant * add module name * Fix GetSignByes, add tests * removed module names from registered messages to match other modules * added interfaces and concrete types registration * unseal amino instances to allow external grant and authorization registration * fixed messages tests * allow to register external types into authz modulecdc * use legacy.Cdc instead of ModuleCdc inside x/authz * move the legacy.Cdc initialization outside init function * added serialization docs * Update docs/core/encoding.md Co-authored-by: Amaury <1293565+amaurym@users.noreply.github.com> * added the Ledger specification * fixed tests Co-authored-by: Amaury M <1293565+amaurym@users.noreply.github.com> (cherry picked from commit 81cfc6c)

+#### Authz authorizations
+
+Since the `MsgExec` message type can contain different messages instances, it is important that developers
+add the following code inside the `init` method of their module's `codec.go` file:
+
+```go
+import "github.com/cosmos/cosmos-sdk/codec/legacy"
+
+init() {
+    // Register all Amino interfaces and concrete types on the global Amino codec so that this can later be
+    // used to properly serialize x/authz MsgExec instances
+    RegisterLegacyAminoCodec(legacy.Cdc)	
+}
+```
+
+This will allow the `x/authz` module to properly serialize and de-serializes `MsgExec` instances using Amino, 
+which is required when signing this kind of messages using a Ledger. 
+
 ### Gogoproto
 
 Modules are encouraged to utilize Protobuf encoding for their respective types. In the SDK, we use the [Gogoproto](https://github.com/gogo/protobuf) specific implementation of the Protobuf spec that offers speed and DX improvements compared to the official [Google protobuf implementation](https://github.com/protocolbuffers/protobuf).
