[XRay][profiler] Part 3: Profile Collector Service
Summary:
This is part of the larger XRay Profiling Mode effort.
This patch implements a centralised collector for `FunctionCallTrie`
instances, associated per thread. It maintains a global set of trie
instances which can be retrieved through the XRay API for processing
in-memory buffers (when registered). Future changes will include the
wiring to implement the actual profiling mode implementation.
This central service provides the following functionality:
* Posting a `FunctionCallTrie` associated with a thread, to the central
list of tries.
* Serializing all the posted `FunctionCallTrie` instances into
in-memory buffers.
* Resetting the global state of the serialized buffers and tries.
Depends on D45757.
