25a7c3fd57 Fix setjmp.bug_152210274 with HWASan/stack MTE enabled. 
This test was flaky because there was no synchronization between the end
of the test function scope and the jumper threads, resulting in a racy
use-after-scope when accessing the thread array. Fix it by joining the
threads before leaving the test function scope.

Replace the thread array access, which can race with the store to the
thread array in the main thread, with an access to a pre-initialized
variable, which acts as a kind of enforcement that the threads are done
before leaving the test.

f1ab9c4de7 Move M_PURGE to M_PURGE_ALL. 
Since it doesn't matter if these calls take a little longer than
before, use the more thorough but slightly longer purge mechanism.

Test: Unit tests pass.

955f04425e Disable stack tagging in CloneStartRoutine. 
We don't support running threads on a tagged stack. Untagging SP may
lead to accesses to the stack via a non-SP register, which will be tag
checked, and the check will fail. And indeed that's exactly what the
__bionic_clone function does in its first instruction. Fix the problem by
disabling HWASan and MTE stack tagging on CloneStartRoutine, and remove
the call to untag_address, as it is unnecessary.

35759fa84c Fix mte build breakage. 
The strerror_buf is way too large, so instead of using a separate
buffer for just this string, reuse the already existing buffer.
Increase the buffer size to cover the maximum errno string.

Add a unit test to verify that none of the errno values are cut off
in the async_safe_format_buffer function when passing %m.

Bug: 274474681

Test: New unit test passes.
Test: Changing the buffer to a small value and verify that the test fails.
