Cleaning up some of the GWP-ASan code base:
- lots of headers didn't have the correct file name
- adding `#ifdef` guard to `utilities.h`
- correcting an `#ifdef` guard based on actual file name
- removing an extra `;`
- clang-format'ing the code (`-style=llvm`)

Summary:
New shard out of the Check() function for GWP-ASan uses
android_set_abort_message. This is happily present on bionic Android,
but not Android for glibc host x86. Fix up to use the weak definition
always, so we don't have to worry.

Summary:
When platforms use their own `LIKELY()` definitions, it can be quite
troublesome to ensure they don't conflict with the GWP-ASan internal
definitions. Just force the GWP_ASAN_ prefix to help this issue.

Summary:
See D60593 for further information.
This patch introduces the core of GWP-ASan, being the guarded pool allocator. This class contains the logic for creating and maintaining allocations in the guarded pool. Its public interface is to be utilised by supporting allocators in order to provide sampled guarded allocation behaviour.
This patch also contains basic functionality tests of the allocator as unittests. The error-catching behaviour will be tested in upcoming patches that use Scudo as an implementing allocator.
