We already return `true` from `[Leyden's target_needs_far_branch()](https://github.com/openjdk/leyden/blob/premain/src/hotspot/cpu/aarch64/macroAssembler_aarch64.cpp#L699) for AOT code generation.

During this PR testing with Leyden I also found that we need to do the same in [codestub_branch_needs_far_jump()](https://github.com/openjdk/leyden/blob/premain/src/hotspot/cpu/aarch64/macroAssembler_aarch64.hpp#L1260)

And now in `is_always_within_branch_range()` too.
