[Sampling profiler] Encapsulate Mac stack walking 3/4: frame recording

The platform-native stack walking needs to be encapsulated into a function that
can be invoked in an alternating fashion with V8 unwinding, once supported. This
change inlines the frame recording into the core stack walking function. The
encapsulation requires inlining otherwise-sensible abstractions to enable
creation of future abstractions that can be used across platforms. No functional
change is intended.
