Improve printing for lambda arguments

[belav]

There are improvements that could be made to printing arguments, namely with lambdas as parameters. #669 stuck to just improving some simple cases (single arguments or parenthesized lambdas with no arguments). Prettier has more complicated logic that we should look into.

A simple lambda with too long of an argument name + a block doesn't break when it should.
Simple lambdas with no block.
Parenthesized lambdas with no block.
Parenthesized lambdas with arguments.

Some examples

            builder.Entity<IdentityUserToken<string>>(b =>
            {
                b.HasKey(
                    l =>
                        new
                        {
                            l.UserId,
                            l.LoginProvider,
                            l.Name
                        }
                );
                b.ToTable("AspNetUserTokens");
            });

                table.PrimaryKey(
                    "PK_AspNetUserTokens",
                    x =>
                        new
                        {
                            x.UserId,
                            x.LoginProvider,
                            x.Name
                        }
                );

this may be more because of breaking with the new { } stuff that came from #755

builder.Entity<EntityWithThreeProperties>(e =>
                {
                    e.HasIndex(
                        t =>
                            new
                            {
                                t.X,
                                t.Y,
                                t.Z
                            },
                        "IX_unspecified"
                    );
