…data RPC and GetProviderSchemaOptional server capability (#311)

Reference: #310

Protocol upgrades that impose new RPCs will either require:

- The `tfprotov5.ProviderServer`/`tfprotov6.ProviderServer` interface to require a new method
- Or, new "optional" interfaces be implemented (let's make up `ProviderServerWithGetMetadata` in this case)

terraform-plugin-go is a low level abstraction which is designed to _directly implement_ the protocol rather than introduce its own abstractions. Most provider developers will directly interface with higher level Go modules, such as terraform-plugin-sdk and terraform-plugin-framework. Except for advanced provider development using this Go module directly, this type of low level "breaking" change will be hidden by also upgrading those Go modules at the same time:

- hashicorp/terraform-plugin-sdk#1235
- hashicorp/terraform-plugin-framework#829
- hashicorp/terraform-plugin-mux#186

Therefore the change is implemented on the existing interface.
