  [tsan] Don't use `enum __tsan_memory_order` in tsan interface (#114724)

In C++ it's UB to use undeclared values as enum.
And there is support `__ATOMIC_HLE_ACQUIRE` and
`__ATOMIC_HLE_RELEASE` need such values.

Internal implementation was switched to `class enum`,
where that behavior is defined. But interface is C, so
we just switch to `int`.
