[GWP-ASan] Integration with Scudo [5].

Summary:
See D60593 for further information.

This patch adds GWP-ASan support to the Scudo hardened allocator. It also
implements end-to-end integration tests using Scudo as the backing allocator.
The tests include crash handling for buffer over/underflow as well as
use-after-free detection.
