Joe Tsai d63652b7c6 log/slog: simplify and optimize RFC3339 handling
In CL 421877 and CL 444278, time.Time.AppendFormat has been
specially optimized for the time.RFC3339Nano representation.
Relying on that optimization and modify the output to obtain the
fixed-width millisecond resolution that slog uses.

This both removes a lot of code and also improves performance:

	name       old time/op  new time/op  delta
	WriteTime  93.0ns ± 1%  80.8ns ± 0%  -13.17%  (p=0.000 n=8+9)
