internal/lsp: fix godef for embedded type aliases


    type myAlias = someType
    type _ struct {

Previously running "definition" on the "myAlias" field would take you
to the definition of "someType" instead of "myAlias". This is because
we were using the field's (*types.Var).Type() which has already
forgotten it is an alias. Fix by instead looking up the field name
ident in types.Info.Uses which yields the *types.TypeName (for the
type alias).

Fixes golang/go#42254.
