std: add option to use single-threaded event loop
std.event.Loop does not yet work in single threaded builds. However, using evented io on a single thread can be very convenient. This commit allows settind @import("root").event_loop_mode to .single_threaded in order to allow this without reimplementing the startup code in start.zig
