Previously, we were trying to memset a pointer that wasn't being
initialized, and the test would randomly fail.
This PR replaces the pointers with actual objects.

Summary:
This patch introduces a lock-free stack used to store a fixed number of
slabs. Instead of going directly through RPC memory, we instead can
consult the cache and use that. Currently, this means that ~64 MiB of
memory will remain in-use if the user completely fills the cache.
However, because we always fully destroy the object, the chunk size can
be reset so they can be fully reused.
This greatly improves performance in cases where the user has previously
accessed malloc, lowering the difference between an implementation that
does not free slabs at all and one that does.
We can also skip the expensive zeroing step if the old chunk size was
smaller than the previous one. Smaller chunk sizes need a larger
bitfield, and because we know for a fact that the number of users
remaining in this slab is zero thanks to the reference counting we can
guarantee that the bitfield is all zero like when it was initialized.

This would ensure that errno value is cleared out before test execution
and tests pass even when LIBC_ERRNO_MODE_SYSTEM_INLINE is specified (and
errno may be clobbered before test execution).
A lot of the tests would fail, however, since errno would end up getting
set to EDOM or ERANGE during test execution and never validated before
the end of the test. This should be fixed - and errno should be
explicitly checked or ignored in all of those cases, but for now add a
TODO to address it later (see open issue #135320) and clear out errno in
test fixture to avoid test failures.

Addressed TODO to template the StringConverter pop functions to have a
single implementation (combine popUTF8 and popUTF32 into a single
templated pop function)
The iswalpha function is only working for characters in the ascii range
right now, which isn't ideal. Also it was returning a bool when the
function is supposed to return an int.
Summary:
We need `malloc` to return a larger size now that it's aligned properly
and we use a bunch of threads. Also the `match_any` test was wrong
because it assumed a 32-bit lanemask.
POSIX says "If no such wide-character code is found, the current token
extends to the end of the wide-character string pointed to by ws1, and
subsequent searches for a token shall return a null pointer", but the
current implementation only returns nullptr the first time. This failed
an existing bionic test when I tried to switch over to llvm-libc
wcstok().
This patch removes some sched.h includes, preferring the proxy headers.
This patch does not clean them all up as some proxy type headers need to
be added, like for `struct sched_param`.
