[GWP-ASan] Change sys/cdefs.h to features.h
sys/cdefs.h is a glibc internal header which is not supposed to be included by applications.
(Some libc implementations provide this file for compatibility.)
Android features.h includes sys/cdefs.h, so we can include features.h instead.
This change makes `ninja gwp_asan` build on musl.

[GWP-ASan] Abstract the thread local variables access
In a similar fashion to D87420 for Scudo, this CL introduces a way to
get thread local variables via a platform-specific reserved TLS slot,
since Fuchsia doesn't support ELF TLS from the libc itself.
If needing to use this, a platform will have to define
`GWP_ASAN_HAS_PLATFORM_TLS_SLOT` and provide `gwp_asan_platform_tls_slot.h`
which will define a `uint64_t *getPlatformGwpAsanTlsSlot()` function
that will return the TLS word of storage.
I snuck in a couple of cleanup items as well, moving some static
functions to anonymous namespace for consistency.

[GWP-ASan] Rework utilities (NFC)
Few changes wrt utilities:
- split `Check` into a platform agnostic condition test and a platform
specific termination, for which we introduce the function `die`.
- add a platform agnostic `utilities.cpp` that gets the allocation
alignment functions original in the platform specific file, as they
are reusable by all platforms.

(https://cs.android.com/android/platform/superproject/+/master:bionic/tests/malloc_test.cpp;l=808),
but the general gist is that for malloc(x <= 8), we do malloc(8), and
for everything else, we do 16-byte alignment.

[GWP-ASan] Crash Handler API.
Summary:
Forewarning: This patch looks big in #LOC changed. I promise it's not that bad, it just moves a lot of content from one file to another. I've gone ahead and left inline comments on Phabricator for sections where this has happened.
This patch:
1. Introduces the crash handler API (crash_handler_api.h).
2. Moves information required for out-of-process crash handling into an AllocatorState. This is a trivially-copied POD struct that designed to be recovered from a deceased process, and used by the crash handler to create a GWP-ASan report (along with the other trivially-copied Metadata struct).
3. Implements the crash handler API using the AllocatorState and Metadata.
4. Adds tests for the crash handler.
5. Reimplements the (now optionally linked by the supporting allocator) in-process crash handler (i.e. the segv handler) using the new crash handler API.
6. Minor updates Scudo & Scudo Standalone to fix compatibility.
7. Changed capitalisation of errors (e.g. /s/Use after free/Use After Free).
