internal/lsp: show a warning message when opening an "orphaned" file

Build tags are a common stumbling block for users of gopls, as build
tagged files may be excluded from the initial workspace load without a
clear warning. This change adds a check for every opened file to confirm
if it maps to a package. If not, we show a message with suggestions.

A follow-up improvement might be to check if the opened file actually
has build tags to make the error message more precise (and give a better
example config).
