Add support for the experimental on-demand tracing
This is to support on-demand tracing. This is behind a flag that is
disabled by default. This is the initial CL that adds support to ART.
There will be a followup CL to add an API that can be used from the
frameworks to request a trace of dex methods that got executed. This is
different from method tracing in two ways:
1. Method tracing is precise whereas this traces on a best effort basis.
2. Unlike method tracing this uses a circular buffer so can only trace a
limited window into the past.
Bug: 352518093
Test: art/test.py
