Corentin Pescheloche 0bf11af7e4 [api][profiler] Surface CpuProfiler memory in HeapCodeStatistics 
The goal of the PR is to add to telemetry a metric estimating the space
occupied by the codemap retained by a CpuProfiler and its underlying
CodeObserver.

This change is motivated by the addition of kEagerLogger to CpuProfiler
which when enabled let a CpuProfiler build a CodeMap without an active
session. This metric will help us understand better the space consumed
by a profiler in that scenario and will also help detect memory leaks.
