Integrate FTrace binary parsers into trace compass incubator

Currently, trace compass uses trace-cmd to convert binary FTrace traces
into text traces, and then processes it. It requires trace-cmd to be
installed on the running machine. Parsing the binary files directly will
allow trace reading to be platform independent.

This commit integrates FTrace parsers into trace compass incubator by
providing trace event reading logic and trace reading context. It also
adds initial tests for integration. The supported FTrace version is
v2.6. Other versions default to trace-cmd reports (legacy way of
working). Test traces for binary FTrace are stored in
tracecompass/tracecompass-test-traces, which is a separate repository.
