RFR: 8283085: AArch64: No need to leave a breadcrumb for JavaFrameAnchor::capture_last_Java_pc when leaf call

[Denghui Dong]

Hi,

Could I have a review of this fix that remove the breadcrumb in `aarch64_enc_java_to_runtime` for `Op_CallLeaf`, `Op_CallLeafNoFP` and `Op_CallNative`.

For more details please refer to the description of the issue.

Thanks,
Denghui
