Enable memory profiler on Linux when TC_MALLOC is enabled.
Added a tc_malloc memory extension to get bytes allocated on
current thread (GetBytesAllocatedOnCurrentThread API call).
R=jam@chromium.org,jar@chromium.org
BUG=139667
TEST=test about:profiler after setting the env variable
CHROME_PROFILER_TIME=1. In about:profiler, it will
show the memory allocated per thread. This change
impacts linux only.
