When using device, the python modules for host are not loaded to be
compatiable in tradefed.
Test: pytest

The time in timestamp is second, while the trace duration is
millisecond. Using timedelta to fix this ambiguity.

The basic idea is add timestamp for MmFilemapAddToPageCache.
Treat the first receiving MmFilemapAddToPageCache timestamp as
the start time. The end time is the sum of start time and duration.
Any MmFilemapAddToPageCache after end time is filtered out.

Compiler will be used for experimentation purpose since it's both easier
to develop in python and it accepts ftrace, making it very easy to write
complicated-experimental changes that we aren't sure are worth it yet
for the on-device C++/perfetto compiler.
This 'new' compiler accepts ftrace/systrace files as input,
then generates an in-memory sqlite3 database (using the trace_analyzer
source code), and finally code-generates a TraceFile.pb protobuf.
(Also refactor trace_analyzer into a library, and update it to
parse systrace.html files)
Limitations: currently does not accept perfetto_trace.pb files due to
'ofs' fields missing (see bug#135555191)
