[compiler-rt][ctx_profile] Add the instrumented contextual profiling APIs ( #89838 )
...
APIs for contextual profiling. `ContextNode` is the call context-specific counter buffer. `ContextRoot` is associated to those functions that constitute roots into interesting call graphs, and is the object on which we hang off `Arena`s for allocating `ContextNode`s, as well as the `ContextNode` corresponding to such functions. Graphs of `ContextNode`s are accessible by one thread at a time.
