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
