[ANGLE] Re-enable PoolAllocator under AddressSanitizer
<https://bugs.webkit.org/show_bug.cgi?id=323682>
<rdar://186936657>
Reviewed by Kimmo Kinnunen.
Restrict the `ANGLE_DISABLE_POOL_ALLOC` bypass to ThreadSanitizer so
that `angle::PoolAllocator` is used again under AddressSanitizer. The
bypass was introduced for both sanitizers in 312740@main; routing
every translator allocation through the system allocator makes ANGLE
pathologically slow under ASan.
`PoolAllocator` already poisons and unpoisons its own redzones through
`__asan_poison_memory_region()` / `__asan_unpoison_memory_region()`,
so ASan continues to detect out-of-bounds access to pool allocations
with the pool enabled, and there is no signal that disabling the pool
helps ASan find additional bugs. Only ThreadSanitizer still requires
the bypass.
