Fixes for the profiler on arm64.
...
On arm64, in Dart code, R18(SP) is the stack pointer.
In C++ code, R31(CSP) is the stack pointer.
The profiler must choose the right one when performing
its bounds checks.
This change also fixes a bug in the InvokeDartCode stub
on arm64 so that CSP is set to the Isolate's stack
limit immediately, rather than a bit later. When it was
set a bit later, if a profiler interrupt came in in the
interim, the stack would be smashed.

* Introduce ThreadInterrupter which calls a TLS set callback when thread is interrupted.
...
* Threads can only register and unregister themselves with ThreadInterrupter.
* Profiler is no longer involved in interrupting threads. It's just a callback and the buffer.
* Profiler operates lock free using an atomic operation to reserve sample in sample buffer.
* Linux, Mac, and Windows done.
