This API allows to programmatically generate timeline information
including profiling samples if timeline format supports it.
This change also includes Perfetto timeline writer and profiler
into non-mobile PRODUCT builds. The size of Mac OS X dartaotruntime
has increased by 34352 bytes (0.7%).
This relands commit 553887bc56 with fixes
for Android builds.
