show fields without default value prior to fields with default value

[dacec354]

Remember to search before filing a new report

example:

const std = @import("std");

const Foo = struct {
    id: i32 = 0,
    name: []const u8,
};

pub fn main() !void {
    const foo: Foo = .{
        .id = 0, // here
        .name = "default",
    };
    std.debug.print("{}\n", .{foo});
}

when I type . popup shows id prior to name. making name first would be more efficient.

additionally, it would be nice if fields shows its default value in popup.
