internal/lsp: add unnecessary tags for unused vars and imports

Diagnostic Tags add another hint for the client for how to
display diagnostics. The Unnecessary tags allows clients to
fade out the diagnostic instead of adding a squiggle. This adds
this tag to unused import errors as well as unused vars.

For golang/vscode-go#2285
