trace: add size_t field emitter

It is not guaranteed that sizeof(long) == sizeof(size_t). On Windows,
sizeof(long) == 4 and sizeof(size_t) == 8 for 64-bit programs.
Tracepoints using "long" field emitter are therefore invalid there.
Add dedicated field emitter for size_t and use it to store size_t values
in all existing tracepoints.
