Add stubs for inlay hint methods (LSP 3.17)

The following are added manually to the generated code:
* inlayHint/resolve
* textDocument/inlayHint

Generating this code is currently not possible since the upstream gopls
generator was migrated from Typescript to Go just before the 3.17 LSP
release. Using the new generator requires some more work and adaptions
on our side.
