[Docs] Add native heap profiling instructions.

[Docs] Add native heap profiling instructions.

Native heap profiling captures C/C++ backtraces for allocations, but
requires a special build (and a symbolization step).

LGTM, sorry forgot about this CL

https://codereview.chromium.org/2084973002/diff/1/components/tracing/docs/hea...
File components/tracing/docs/heap_profiler.md (right):

https://codereview.chromium.org/2084973002/diff/1/components/tracing/docs/hea...
components/tracing/docs/heap_profiler.md:48: enable_profiling = true
Should we suggest also  enable_full_stack_frames_for_profiling ?
The gn doc says that it has major perf implications, not sure how slower does
this make it.
Maybe suggest as optional

https://codereview.chromium.org/2084973002/diff/1/components/tracing/docs/hea...
components/tracing/docs/heap_profiler.md:84: (note `--output-directory` and make
sure it's right for your setup)
I think this note is really redundant :)
