gh-131675: Fix `mi_atomic_yield` in mimalloc on 32-bit ARM (gh-131784)

Use the standard `__ARM_ARCH` macro, which is supported by GCC and Clang.

The branching logic for of `__ARMEL__` has been removed so if the target
architecture supports v7+ instructions, a yield is emitted, otherwise a nop
is emitted. This covers both big and little endian scenarios.
