AArch64: Prioritise init_have_lse_atomics constructor [PR 105708]

Increase the priority of the init_have_lse_atomics constructor so it runs before other constructors. This improves chances that rr works when LSE atomics are supported. libgcc/ PR libgcc/105708 * config/aarch64/lse-init.c: Increase constructor priority.
