Hi,
This CL adds memory capture support for macOS, similar to the existing
Windows and Linux implementations. It captures memory regions referenced
by CPU register values to improve crash analysis.
Would appreciate your review. Thanks!

this needs a macOS expert to look at it and my expertise is in Windows, so you might have to find someone.
this might also need a security or privacy review if we are expanding the memory being captured, to make sure it's no more than is needed and functionally equivalent to other platforms.
