lsp: add client/registerCapability handler (#13780)

Browse Source 
Until we support dynamicRegistration, we should handle the client/registerCapability in core. There are still some language servers that send this request despite dynamicRegistration not being registered client-side (we got an upstream fix for the node ones, but this depends on them bumping vscode-languageserver-node).
