Dan Liew dd922bc2a6 [LSan] Introduce a callback mechanism to allow adding data reachable from ThreadContexts to the frontier. 
This mechanism is intended to provide a way to treat the `arg` pointer
of a created (but not yet started) thread as reachable. In future
patches this will be implemented in `GetAdditionalThreadContextPtrs`.

A separate implementation of `GetAdditionalThreadContextPtrs` exists
for ASan and LSan runtimes because they need to be implemented
differently in future patches.

Matt Morehouse 7904bd9409 [sanitizer_common] Create max_allocation_size_mb flag. 
Summary:
The flag allows the user to specify a maximum allocation size that the
sanitizers will honor.  Any larger allocations will return nullptr or
crash depending on allocator_may_return_null.
