Permits measuring times from start of recording (usually start of a
call), and not time from first event that occurs after tracing starts.

Incorrect argument order, also added unittest which should've been there
in the first place.
Also renames AtomicLoadPtr to AcquireLoadPtr to match non-ptr version.

rtc::PlatformThreadId is pid_t (32-bit signed int) on Linux and Mac,
but DWORD (32-bit unsigned int) on Windows.
Using the %d printf specifier is therefore not correct on Windows,
and Clang would warn about it:
..\..\third_party\webrtc\base\event_tracer.cc(124,46) : error: format specifies
type 'int' but the argument has type 'rtc::PlatformThreadId' (aka 'unsigned
long') [-Werror,-Wformat]
e.phase, e.timestamp, e.pid, e.tid);
^~~~~
This commit fixes the problem by explicitly casting to int before printing.

Logs tracing events (TRACE_EVENT0 and friends) to storage in a format
compatible with chrome://tracing which can be used for performance
evaluation, finding lock contention and other sweet things). Tracing is
still basic and doesn't contain thread metadata or logging of tracing
arguments.
