internal/lsp: don't resend diagnostics if they are unchanged

Cache delivered diagnostics on the server so that we can determine if
they should be resent. To be careful about this, we only reuse cached
diagnostics if they are for a greater version, or if we don't know
the file's version and it is unchanged.

Fixes golang/go#32443
